How to guide on setting up Seafile server 3.1.7 on a fresh install of Ubuntu server 20.04 LTS

Introduction

This guide shows how to perform a fresh install of Ubuntu server 20.04 LTS with a LXQT virtual desktop and Seafile server 3.1.7. The steps are numbered such that people can easily refer to a certain step in a question/discussion. Note that when copying commands from the guide into the terminal, it is best to copy it one line at a time. To paste into a terminal use ctrl+shift+v.
The Ubuntu server has as sole purpose to host Seafile, nothing else. I could not find a comprehensive guide for it so I pieced bits and pieces that I found online to the guide that is shown below. It is very specific and provides some additional information here and there such that users who are new to Ubuntu are also able to follow along.
I struggled quite alot with the installation of Ubuntu server and Seafile which is one of the reasons I decided to write this guid. I even managed to delete my entire Seafile backup on accident... terabytes of data, fallen to the might of a wrongly executed 'rm' command... to be lost forever.
Section 1 will guide you through the installation of Ubuntu server 20.04 LTS; section 2 shows how to install the LXQT desktop environment on it; in section 3 the settings of the router are changed such that the server has a static local IP and (optionally) can be accessed from outside the local area network; in section 4, I will guide you through the installation of MariaDB; in section 5, Nginx is installed; section 6 is the installation of the dependencies of the Seafile server; finally in section 7, Seafile is installed; in section 8 I will show you how to generate a certificate and in section 9 https will be setup in Nginx.

1. Fresh install of Ubuntu server 20.04 LTS

1.1 Download Ubuntu server 20.04 LTS (link)
1.2 Create live USB/CD (link)
1.3 During boot press F2 (or other key to change boot device) and boot from USB/CD
1.4 Select language (english)
1.5 Select keyboard layout (english us)
1.6 Configure network connections: Leave at default > done.
1.7 Proxy: leave empty > done
1.8 Mirror address: leave at default > done
1.9 Storage layout: use entire disk. Warning, all data of the selected disk will be lost!
1.10 Available devices: leave at default OR if the seafile-data is stored on a seperate disk: goto desired partition of device (should say 'not mounted'). select and hit enter > edit > mount > other > enter '/seafile-data' (or other mount location) > save. Then click 'done' > 'continue'. WARNING: make sure that the disks that are to be formated are backed up!
1.11 Profile setup
  • Your name: main-user
  • Your server's name: server
  • Pick a username: main-user
  • password:
  • confirm your password:
1.12 ssh setup: leave unchecked > done (unless you want to use ssh ofcourse).
1.13 server snaps: leave everything unchecked > done
1.14 wait for system to install
1.15 select reboot and hit enter
1.16 Wait for the message ' Please remove installation medium' to appear and remove USB/CD , then press enter
1.17 Wait for it to boot, when the login screen appears, wait a bit more because in my case Ubuntu kept loading stuff. After it is truly booted, press this causes 'server login' to reappear.
  • server login: main-user
  • password:
1.18 Make sure system is up to date and reboot
sudo apt update sudo apt upgrade sudo apt autoremove sudo reboot 
1.19 Login again.

2. Setup virtual desktop

2.1 Install trash. I recommend to always use 'trash' instead of 'rm'. 'rm' makes it easy to mess up the entire Ubuntu installation or to perminently delete valuable data with only a small mistake. I unrecoverably lost the entire seafile-data backup (terabytes of data) due to this. Trash however, moves deleted files to the trash-bin, so upon deleting a file or directory it is still recovarable (this is not the case with rm).
sudo apt install trash-cli 
2.2 Install lxqt and sddm, lxqt is an extreme light desktop environment and sddm stands for simple desktop display manager, which is required for running lxqt. Alternatively to installing Ubuntu server + LXQT, Lubuntu 20.04 can be installed instead. I prefer Ubuntu + LXQT is because lubuntu only has support until 2023 whereas Ubuntu server 20.04 has support to 2025.
sudo apt install lxqt sddm 
2.3 Select 'sddm' and hit 'enter'. gdm3 stands for Gnome desktop manager 3. Gnome is also a desktop environment like lxqt, but it requires more memory and process-power. If you selected the wrong one, let it install and typ in the following
sudo dpkg-reconfigure sddm 
2.4 Reboot
sudo reboot 
2.5 Log in
2.6 If prompted with which window manger to use, select 'Mutter' which is the default window manager.
2.7 To disable screensaver: menu > preferences > screensaver > mode: disable
2.8 Configure autologin and relogin. I configured my bios to boot if there is an AC outage, this however has no use if the server does not autologin and autostart seafile. Relogin is optional, if the main-user happens to log out, this makes sure main-user is automatically logged in again. First make sure that lxqt exists as a session.
ls /usshare/xsessions -1 
This should list 'lxqt.desktop' and 'ubuntu.desktop'. Remember that 'sddm' is installed, to open its configuration file open a terminal and type in the following:
sudo nano /etc/sddm.conf 
The file you are seeing should be empty, now add the following lines.
[Autologin] User=main-user Session=lxqt.desktop Relogin=true 
If you are new to the nano editor, the '^' key means the 'ctrl' key. Save the file 'ctrl+s' and close it 'ctrl+x'.
2.9 Reboot to see if it works.
sudo reboot 
2.10 Create seafile user. The server is supposed to be always on and always logged in, so as a preventive measure to limit access to the Seafile settings and files, a seafile user is created. The ownership of the Seafile installation and settings will be limited to that user only.
sudo useradd seafile -p  
If you mispelled the name you can use 'sudo userdel ' to delete it. To see the existing users & groups use the command 'sudo cat /etc/group', this will display all the users and groups whereas the commands 'groups' and 'users' do not.

3. Router setup

3.1 Give the server a static local IP, otherwise it is possible that the local IP of the server changes on server reboot or router reboot. I assigned a static local IP to the server from my router by using the MAC adress of the server. A MAC address is hardcoded into network devices and can be used to identify them.
3.1.a To obtain the MAC address of the server open a terminal and type in:
ip addr show 
This shows a list with information about the interface devices. 'lo' stands for loopback which is not of interest, if the name starts with 'e' (like eth0 or enp2s0) it usually indicates ethernet, if the name starts with 'w' it usually indicates wireless. Obtain the MAC address of the interface device that is used, this is displayed in hex-form and looks like XX:XX:XX:XX:XX:XX , with the X's being numbers or the letters a-f. The mac adress should be displayed right after link/ether.
3.1.b Go to your router settings, this can be done by opening a webbrowser and typing in the IP of your router. This is often, 192.168.0.0 , 192.168.0.1 , 192.168.2.254 or something along those lines.
3.1.c If prompted with a login, search online what the password is, this is often or admin.
3.1.d Find the page of the DHCP settings. DHCP stands for dynamic host configuration protocol, it is responsible for appointing a local IP to all the device connected to it, like the server. This page can often be found under Internet or LAN settings.
3.1.e Somewhere on the page there should be an option to bind the MAC address of the server to a static local IP, this is called DHCP binding. Fill in the MAC address and the IP you would like to give the server, I choose to use 192.168.2.100 but note that this IP should lie within the range of the DHCP.
3.2 Forward seafile and seahub ports to the server if you want to access the server from outside the local area network (LAN).
3.2.a first go to the page of 'port forwarding' this should be located somewhere under internet or LAN settings.
3.2.b Now assign the ports '8080' (seafile) and ' 443' (seahub, port for https). Seafile is the actual file-server and seahub is the web interface for it. If you do not want to use the web interface, forwarding port 443 can be omitted. Note that seahub uses port 8000 by default, but later on in this guide https will be setup such that port 433 (default port of https) is used instead.

4. Install and setup MariaDB

Seafile works with databases sqlite and mysql. I'm no expert in the matter, but from what I can find online is that mariadb (mysql) is considered to be better when a large amount of users are involved. Even though my server will not host many users, I considered it to be best practice to use mariadb (mysql) nonetheles. Mysql has been bought by Oracle and now contains some propietary code in it, since I'm a fan of open source I opted for the popular alternative MariaDB, which is a fork of mysql and is similar in use.
4.1 Open a terminal and install mariaDB by typing in:
sudo apt install mariadb-server mariadb-client 
4.2 Check if MariaDB is running by typing the following in a terminal
systemctl status mariadb 
4.3 Check if you are able to login into mariadb as root (note that the command mysql is used but it is still mariadb)
sudo mysql -u root 
To exit it, type 'exit'.
4.4 The default settings of MariaDB has remote login enabled and some other unsafe settings. To change this run
sudo mysql_secure_installation 
This runs a script that asks a couple of questions, answer them as follows:
Enter current password for root (enter for none):  Set root password? [y/n] y New password:  Re-enter new password:  Remove anonymous users? [y/n] y disallow root login remotely? [y/n] y Remove test database and access to it? [y/n] y Reload privilege tables now? [y/n] y 
4.5 Now restart MariaDB
sudo systemctl restart mariadb 
4.6 Check if it is running (it is possible that ctrl+c needs to be pressed after the command)
systemctl status mariadb 
NOTE: even though we set a root password, I am still able to login without a password (sudo mysql -u root) and I am not able to login from main-user, even though I am providing a password (mysql -u root -p > access denied). Because of this, the seafile setup script we need to run later on, has to be run with sudo.

5. Install Nginx

5.1 Open a terminal and run
sudo apt install nginx 
5.2 Check if nginx is running by typing in the following into a terminal
systemctl status nginx 
5.3 Check if it works correctly by opening a browser and visiting 'localhost'. This should display the welcome page of nginx.
5.4 Check if the static ip that is assigned during router setup (step 3.1) is done correctly. Open up a broswer on a different device (laptop/pc/phone) and visiting the local IP that was assigned (192.168.2.100 in my case)
5.5 Check if the port forwarding during the router setup (step 3.2) is done correctly. Open up a browser on a different device and visit the global IP (click here to find your global IP).

6. Install Python dependencies

6.1 Install the following packages from the terminal using apt install. Note: refrain from installing python-packages with apt since they come from the Ubuntu repository and can lack behind packages that are installed using pip3. For me this was the cause of a Seahub error, the code tried to import a module that did not exist yet in the Ubuntu-repo version.
sudo apt install python3 python3-pip python3-sqlalchemy python3-ldap python3-urllib3 libpython3.8 python3-setuptools python3-mysqldb python3-requests ffmpeg memcached libmemcached-dev 
6.2 Install the following packages from the terminal using pip3 (source).
sudo pip3 install Pillow pylibmc captcha jinja2 sqlalchemy psd-tools django-pylibmc django-simple-captcha python3-ldap 
Note: use sudo with pip3 such that the packages are installed for all users (/usbin/) , otherwise they are installed only for the local user (/home/main-use.local/bin). This will cause a warning to be displayed saying that the directory '/home/main-ude.local/bin' needs to be added to the system path variable. If you prefer installing it for the local user instead, open 'sudo nano /etc/environment' and add '/home/main-use.local/bin' to the PATH.
6.3 Update again and reboot (this step is more a precaution and not really necessary).
sudo apt update sudo apt upgrade sudo apt autoremove sudo reboot 

7. Install Seafile

I opted to install seafile to the '/opt' directory, alternatively it can be installed to '/uslocal' or any other directory of your choice, just make sure to edit the paths where necessary.
7.1 Download Seafile server 3.1.7 to the Downloads folder of the current user. This link is likely to become invalid in the future (this article was written in may 2020). For an up-to-date link: visit the Seafile website (link) > goto the sectin of Seafile server > right click the latest version > copy link-location > replace the link of the command below with this one (press ctrl+shift+v to paste into the console).
wget -O ~/Downloads/seafile.tar.gz "https://s3.eu-central-1.amazonaws.com/download.seadrive.org/seafile-server_7.1.3_x86-64.tar.gz" 
Note: The sign ' ~ ' is a link to '/home/'
7.2 Create a seafile directory in the opt folder and extract the Seafile server package to it
sudo mkdir /opt/seafile sudo tar -xzf ~/Downloads/seafile* -C /opt/seafile 
Note the character ' * ' is a wildcard, meaning that it searches for a file starting with 'seafile' and does not care about anything that comes after it.
7.3 Check if the unpacking was done correctly
sudo ls /opt/seafile -1 
This should print the folder 'seafile-server-7.1.3' (if the link was changed, the version should be different).
7.4 Move the downloaded tar file to the trash bin.
trash ~/Downloads/seafile* 
7.5 Move to the seafile dir and install it, it is possible that you need to change the version number if you downloaded a more recent version.
cd /opt/seafile/seafile-server-7.1.3 sudo ./setup-seafile-mysql.sh 
Note that this setup HAS to be run as root (sudo), this is because logging into the mysql root account requires the sudo command as previously mentioned. This script will use the mysql root account to create a seafile mysql account. When running the script, several questions will be asked.
WARNING: THE MYSQL SEAFILE PASSWORD IS STORED AS PLAIN TEXT.
If you answered a question but would like to change it, press 'ctrl+c' and run the script again. For I used my global IP (click here to see what your global IP is) since I will use seafile outside LAN. If you are planning to only use seafile within LAN, use the static local IP that you gave your server when configuring your router.
What is the name of this server? fileserver What is the ip domain?  What port do you want to use for the seafile fileserver?  Please choose a way to initialize seafile databases: 1 What is the host of mysql server?  What is the port of mysql server?  What is the password of the mysql root user?  Enter the name for mysql user of seafile.  Enter the password for mysql user 'seafile':  Enter the database name for ccnet-db:  Enter the database name for seafile-db:  Enter the database name for seahub-db:  Press enter to continue:  
WARNING: the mysql seafile PASSWORD is stored in PLAIN TEXT in the files '/opt/seafile/conf/ccnet.conf' and 'opt/seafile/conf/seahub-settings.py'.
7.6 Move to the seafile directory and start seafile and seahub.
cd /opt/seafile/seafile-server-latest sudo ./seafile.sh start sudo ./seahub.sh start 
7.7 When running seahub for the first time it will create an admin account and asks for an e-mail adress and password.
7.8 If you got the warning "LC_ALL is not set in ENV, set to en_US.UTF-8" then add it to the environment. First open the environment settings file.
sudo nano /etc/environment 
This file should not be empty, the first line should say PATH="<...>" (with <...> some paths). Add the following line below it and make sure not to change the path!
LC_ALL=en_US.UTF-8 
Reboot to apply the changes (logging out and back in will also suffice).
sudo reboot 
7.9 Check if mariadb and nginx are running (its possbile that you need to press 'ctrl+c'), then (re)start seafile and seahub
systemctl status mariadb systemctl status nginx cd /opt/seafile/seafile-server-latest sudo ./seafile.sh restart sudo ./seahub.sh restart 
If seahub failed to start then it is likely that one or more necessairy python-packages are missing, this should not happen if you are installing Seafile server 7.1.3, but if you are installing a later version this is possible. Check the Seafile manual (link) for the required packages. Restart seahub after installing these.
7.10 Check if seahub is working correctly by opening a webbrowser and visiting localhost:8000'. You cannot continue to the next step if this is not working properly.
If 'Internel server error' is shown, check the logs in the directory '/opt/seafile/logs'. If the error occurs in a file that ends with '.py', then this is a python file. These errors often involve 'cannot import' which means that a python-package is either not installed, the wrong version is installed or there is a conflict between two packages in which the installation of one packages overwrites (some) files of another package (was the case for me with captcha and django-recaptcha). After installing a package make sure to restart seahub
Tip1: google search the module name that could not be imported, this should provide you with the information on which python-package should be installed or which is giving you trouble.
Tip2: If the python package is installed, it is possible that it is the wrong version. To list the python-packages that are installed using apt, type the following into a terminal
dpkg --list | grep python. 
To list the python packages that are installed with pip3, type the following into a terminal.
pip3 list 
Tip3: If the package has the right version, it is possible that it is installed for a different python version. There error in the seahub.log file should contain a path in which you can find the python version (like python 3.8) that the package should be. To see the Python version of an installed package, type in the following in a terminal ( is the package name).
pip3 show  
The location-path indicates the python version it is installed for (Seafile 3.1.7 uses Python 3.8 from what I can tell).
Tip4: Some python packages will overwrite other packages. For example if seahub displays the error 'cannot import Captchafields from captcha.fields in ' then open the python file provided by the patch and check which classes/functions are present in it (for me the only class present was reCaptchaFields). Next google those classes to see to which python module they belong and uninstall that module. A package can be uninstalled using the following command
sudo pip3 uninstall  
To forcefully reinstall the package that was overwritten by the package we just uninstalled, use the following command
sudo pip3 install --upgrade --force-reinstall --no-deps  
Tip5: Remember to restart seahub after each package (re)install
cd /opt/seafile/seafile-server-latest sudo ./seahub.sh restart 
7.11 The current ownership of the seafile directory is root, but it is considered bad practice to run programs (so also seafile and seahub) as root. Type in the following into a terminal to change the ownership of the seafile install directory to the seafile account that was created in step 2.10.
sudo chown -R seafile:seafile /opt/seafile 
Type in the following command to see if it worked
ls -l /opt/seafile 
WARNING: do NOT run the command CHMOD on the seafile directory since the seafile mysql password is stored in plain text in several files and you do not want that any user is able to see this.
7.12 Check if seafile and seahub can be (re)started without problems. Note that the seafile user is now required to start these services.
cd /opt/seafile/seafile-server-latest sudo -u seafile ./seafile.sh restart sudo -u sefaile ./seahub.sh restart 
7.13 Assuming this works, we can make a system service to make it easier to (re)start/stop seafile and seahub. First create a system service file for seafile.
sudo nano /etc/systemd/system/seafile.service 
Add the following to it
[Unit] Description=seafile After=network.target mariadb nginx [Service] Type=forking ExecStart=/opt/seafile/seafile-server-latest/seafile.sh start ExecStop=/opt/seafile/seafile-server-latest/seafile.sh stop User=seafile Group=seafile [Install] WantedBy=multi-user.target 
Now do the same for seahub
sudo nano /etc/systemd/system/seahub.service 
add the following to it
[Unit] Description=seahub After=network.target mariadb nginx seafile.service [Service] Type=forking ExecStart=/opt/seafile/seafile-server-latest/seahub.sh start ExecStop=/opt/seafile/seafile-server-latest/seahub.sh stop User=seafile Group=seafile [Install] WantedBy=multi-user.target 
Restart seafile and see if it is running without errors or warnings
sudo systemctl restart seafile systemctl status seafile 
Do the same for seahub
sudo systemctl restart seahub systemctl status seahub 
7.14 Now enable both seafile and seahub such that they start on boot.
sudo systemctl enable seafile sudo systemctl enable seahub 
7.15 Reboot and check if seafile and seahub are running
sudo reboot systemctl status seafile systemctl status seahub 

8. Generate SSL certificate

If you already have a certificate: create the directory 'opt/seafile/key_and_certificate', place them in it with the names 'seafile_server.key' and 'seafile_server.crt' and move on to section 9. enable https with nginx. If you do not have a certificate follow the steps below.
8.1 make sure openssl is installed
sudo apt install openssl 
8.3 Create a directory key_and_certificate in the seafile folder and move into it
sudo mkdir /opt/seafile/key_and_certificate cd /opt/seafile/key_and_certificate 
8.2 Generate certificate, fill in your own global IP
sudo openssl req -new -x509 -sha3-256 -nodes -days 1825 -newkey rsa:2048 -keyout seafile_server.key -out seafile_server.crt 
  • req means a request for a new certificate; x509 means that it is a multipurpose certificate.
  • sha3-256 is the hash function, sha stands for secure hash algorithm, sha3 is the third and most recent version of sha (released in 2015), 256 is the hash output size, alternatively sha3-384 or sha3-512 can be used but this requires more computation power and memory used, I recommend using sha3-256 unless you really really want to keep your stuff secret from the goverment.
  • nodes stands for 'no DES' with DES meaning data encryption standard, without this argument the key will be stored in an encrypted container and a password needs to be entered to open it on every boot.
  • days 1825 is the number of days that the key will be valid. I set it to 5 years, this is when Ubuntu 20.04 LTS support will end and when I will probably reinstall Seafile (or another file-server) again.
  • newkey rsa:2048 is the key generator, RSA is an asymmetric encryption algorithm meaning that a different key is used to encrypt and decrypt. AES is more secure but it is a symmetric encryption algorithm, meaning that the same is used for encryption and decryption.
  • keyout is the output file of the key it is stored in the current folder.
  • out is the output file of the generated certificate and is stored in the current folder.
8.3 The previous command will ask some info that will be included in the certificate, these questions are shown below. Note that you have the option to not answer a question and to leave it blank.
Country name (2 letter code): NL State or Province name (full name):  Locality name (eg, city) []:  Organization name (eg, company) [Internet Widgits Pty Ltd]: Private Organizational Unit Name (eg, section) []:  Common Name (e.g. server FQDN or YOUR name) []:  Email Address []:  
8.4 Verify that the keys are stored in the correct folder
ls /opt/seafile/key_and_certificate -1 
This should output ' seafile_server.key' and ' seafile_server.crt'
8.4 Move out the directory key_and_certificate and change the folder permissions such that only Nginx can access it, nginx has user and group name www-data. 700 means that the user (nginx) has only read, write and execute permission. The first 0 means that other users of that group (which don't exist) and the second 0 means that all other users outside the group do not have access. The -R means recursively, so not only the permissions of the folder are set but also everything in it.
cd /opt/seafile sudo chown -R www-data:www-data /opt/seafile/key_and_certificate sudo chmod -R 400 /opt/seafile/key_and_certificate 
8.5 Verify that the permissions are set correctly
ls -l /opt/seafile 
It should say the following for the directory 'key_and_certificate', the <...> is the size and date.
drwx------ 2 www-data www-data <...> key_and_certificate 

9. Setting up https in Nginx

9.0 create folder for th nginx logs
sudo mkdir /opt/seafile/logs_nginx 
change the ownership to www-data, which is the username of nginx
chmod -R www-data:www-data /opt/seafile/logs_nginx 
9.1 Create nginx configuration file for the seahub website:
sudo nano /etc/nginx/sites-available/seafile.conf 
and enter the lines shown below. The server_name is an underscore (_) , see the nginx documentation for more information on this (link). WARNING: it is possbile that copy pasting this code will give some faulty ' , " or EOL characters. If this is the case, delete and rewrite them manually. Type ctrl+shift+v to paste in the nano editor.
log_format seafileformat '$http_x_forwarded_for $remote_addr [$time_local] "$request" $status $body_bytes_sent "$http_referer" "$http_user_agent" $upstream_response_time'; server { listen 80; server_name localhost; rewrite ^ https://$http_host$request_uri? permanent; # force redirect http to https server_tokens off; # disable printing ngxinx version on error page } server { listen 443 ssl; server_name _; ssl_certificate /opt/seafile/key_and_certificate/seafile_server.crt; ssl_certificate_key /opt/seafile/key_and_certificate/seafile_server.key; server_tokens off; proxy_set_header X-Forwarded-For $remote_addr; location / { proxy_pass http://127.0.0.1:8000; proxy_set_header Host $host; proxy_set_header X-Real-IP $remote_addr; proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; proxy_set_header X-Forwarded-Host $server_name; proxy_read_timeout 1200s; client_max_body_size 0; # used for view/edit office file via Office Online Server access_log /opt/seafile/logs_nginx/seahub.access.log seafileformat; error_log /opt/seafile/logs_nginx/seahub.error.log; } location /seafhttp { rewrite ^/seafhttp(.*)$ $1 break; proxy_pass http://127.0.0.1:8082; client_max_body_size 0; proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; proxy_connect_timeout 36000s; proxy_read_timeout 36000s; proxy_send_timeout 36000s; send_timeout 36000s; access_log /opt/seafile/logs_nginx/seafhttp.access.log seafileformat; error_log /opt/seafile/logs_nginx/seafhttp.error.log; proxy_request_buffering off; # disable proxy buffering since it does not work well when uploading files >4GB } location /media { root /opt/seafile/seafile-server-latest/seahub; } } 
9.2 Remove the default nginx symbolic link and create a link to the previously created seafile.conf file.
sudo trash /etc/nginx/sites-enabled/default sudo ln -s /etc/nginx/sites-available/seafile.conf /etc/nginx/sites-enabled/seafile.conf 
Check if the symbolic link is created correctly and that the symbolic link to the default nginx file is deleted.
ls /etc/nginx/sites-enabled -1 
The output should be 'seafile.conf' and it should be displayed in green, if it is red the symbolic link is invalid. Also, 'default' should not be outputed since it should be removed.
9.3 update ccnet.conf
sudo nano /opt/seafile/conf/ccnet.conf 
remove the port behind service_url , this should look as follows but with a different IP. Note, make sure that it is https not http.
SERVICE_URL = https://192.168.2.100 
9.4 update settings_seahub.py
sudo nano /opt/seafile/conf/seahub_settings.py 
Add this line but change the IP to your own. Make sure that it is https not http
FILE_SERVER_ROOT = 'https://192.168.2.100' 
9.5 Start/restart seafile, seahub and nginx and check if they are running (use the arrows to move down when displaying the status)
sudo systemctl restart nginx seafile seahub systemctl status nginx seafile seahub 
Status should also show more info on an error if it occured. It is likely that the 'etc/nginx/sites-enabled/seafile.conf' file has errors due to copy-pasting from the website. Replace all ' , " and EOL (end of line: ) characters and try restarting nginx. Alternatively, something could have went wrong when generating the ssl certificate or during modifying the folder permissions of 'key_and_certificate'
9.6 Check if it works by opening your browser and vising ' localhost' , note that you may have to clear the cache, history, cookies etc. from your browser if it still displays the default nginx page.

Conclusion

That is it, you should now be able to access the seahub web page using the local IP or global IP depending on your router configuration. Note that since the certificate is self-signed, the browser will display a warning. Same for the seafile client, after installing the Seafile client you will need to go to its settings > advanced tab > and check 'do not verify server certificate in HTTPS syncing.
Note, it is possible that I made some spelling mistakes in the code since I wrote this guide on a separate laptop during the installation.

HELP! TLS Handshake failed Issue with OpenVPN on Raspi

PLEASE HELP!
I am going totally crazy here trying to solve this issue. I have gone down the rabbit hole several times, taken a few months off, and taken another run at it all to no avail. Every resource I find seems to suggest that PiVPN is a breeze to setup but it's NEVER been even remotely successful when I try it. I'm losing my mind over this.

Every time I try to connect, regardless of my configs, I get the same dreaded "TLS handshake failed". My ports are forwarded correctly, and I have installed and reinstalled ad-nauseum to change settings and configs but NOTHING is working.

Here is some info on my setup:

tl:dr My pivpn returns a TLS handshake failed error no matter what I try. Any thoughts?
