Install qBittorrent on Ubuntu 19.04 Desktop via PPA

qBittorrent is included in the default Ubuntu software repository. You can easily install it on Ubuntu 19.04 desktop by running the following command in a terminal window.

sudo apt install qbittorrent

However, it is outdated (v4.1.5). The latest version 4.1.6 was released on May 6, 2019. To get the latest version of qBittorrent, you need to install it from the official qBitorrent PPA (Personal Package Archive). First, run the following command to add the PPA.

sudo add-apt-repository ppa:qbittorrent-team/qbittorrent-stable
qbittorrent ubuntu 19.04

Press Enter to continue. It will update the software repository index. After that, run the following command to install the latest version of qBittorrent.

sudo apt install qbittorrent

This PPA also works on other Linux distributions that are based on Ubuntu, such as Linux Mint and Elementary OS. If your system already has qBittorrent installed, then the above commands will update qBittorrent to the latest version. Don’t worry, your existing torrents are safe. Once installed, you can start qBittorrent from application menu.

How to Enable qBittorrent Web UI on Ubuntu 19.04 Desktop

The web UI allows you to remotely control qBittorrent in a web browser.

  1. In the qBittorrent application window, go to tools > Preferences > Web UI.
  2. Tick on the Web User Interface (Remote Control) option.
  3. You can also choose to use UPnP/NAT-PMP to forward the port from your router, so that you will be able access qBittorrent from outside network.
  4. By default, the web UI is accessible on port 8080. If there’s another service using port 8080, you need to change the port number in qBittorrent.
  5. Set a username and password. (By default “admin” and “adminadmin” respectively).
  6. At the bottom, you can also choose to use one of two dynamic DNS services: DynDNS and No-IP.
  7. Click Apply button.

Now in my local network, I can access qBittorrent web interface via

qbittorrent webui

If you are going to access qBittorrent from outside network, then make sure you have enabled UPnP/NAT-PMP and you will need to enter something like below in the web browser.

Replace with the public IP address of your router.

Make qBittorrent Automatically Start at System Boot Time

To enable autostart, open the Startup Applications from your applications menu. It can also be launched by issuing the following command  in the terminal window.


Then click Add button to add a new startup program. In the Name field, you can enter something like “qBittorrent”. In the Command field, enter /usr/bin/qbittorrent. You can leave the comment field blank. After that, click Add button.

How to Install qBittorrent on Ubuntu 19.04 Server

You can install qBittorrent command line client on a headless Ubuntu 19.04 server and manage it via the qBittorrent web interface (You control it in a web browser). SSH into your Ubuntu 19.04 server and use the same PPA to install qBittorrent daemon.

sudo add-apt-repository ppa:qbittorrent-team/qbittorrent-stable

sudo apt install qbittorrent-nox

Note that we need to install qbittorrent-nox (without X), instead of qbittorrent. qBittorrent-nox is meant to be controlled via its feature-rich Web UI which is accessible as a default on http://localhost:8080. The Web UI access is secured and the default account username is “admin” with “adminadmin” as a password. You can start qBitorrent-nox with:


However, starting qBittorrent-nox this way isn’t recommended, because you can’t run other command while it’s running. Press Ctrl+C to quit it now. We can create a systemd service unit so it can run in the background and also start at system boot time.

Create the qbittorrent-nox user and group so that it can run as an unprivileged user, which will increase your server’s security.

sudo adduser --system --group qbittorrent-nox

The --system flag means we are creating a system user instead of normal user. A system user doesn’t have password and can’t login, which is what you would want for a torrent client. A home directory /home/qbittorent-nox will be created for this user. You might want to add your user account to group qbittorrent-nox with the following command so that the user account has access to the files downloaded by qBittorrent-nox. Files are downloaded to /home/qbittorrent-nox/Downloads/  by default. Note that you need to re-login for the groups change to take effect.

sudo adduser your-username qbittorrent-nox

Then create a systemd service file for qbittorrent-nox with your favourite text editor such as nano.

sudo nano /etc/systemd/system/qbittorrent-nox.service

Copy and paste the following lines into the file. If there’s another service using port 8080, then you need to change the port number for qBitorrent to something else like 8081. Also note that the -d (daemonize) option is needed in this systemd service unit.

Description=qBittorrent Command Line Client

#Do not change to "simple"
ExecStart=/usr/bin/qbittorrent-nox -d --webui-port=8080


To save a file in Nano text editor, press Ctrl+O, then press Enter to confirm. Press Ctrl+X to exit. Now start qBittorrent-nox with the following command.

sudo systemctl start qbittorrent-nox

Note that if you change a systemd service file, you need to reload the systemd daemon for the change to take effect.

sudo systemctl daemon-reload

You might also want to enable auto start at system boot time.

sudo systemctl enable qbittorrent-nox

Check its status:

systemctl status qbittorrent-nox

qbittorrent-nox systemd autostart

You can see that qBittorrent-nox is running and auto start at boot time is enabled.

Accessing qBittorrent Web UI

To access the qBittorrent Web UI from local network, enter the Ubuntu server’s private IP address followed by the port number like below.

Username is admin. Default password is “adminadmin”.

install qbittorrent ubuntu server

The default web interface.

qbittorrent as a service ubuntu

It’s strongly recommended to change the default username and password. Go to Tools > Options and select the Web UI tab. Under the Authentication section, change both username and password.

qbittorrent-nox config file

And now you can start downloading torrents on your Ubuntu 19.04 server. You have the option to upload local torrents or add magnet links. Files are downloaded to /home/qbittorrent-nox/Downloads/  by default.

Using External Hard Drive as the Download Destination Folder

You can change the default download destination folder in Tools -> Options -> Downloads. In order to download torrrent, the qbittorrrent-nox user needs to have write permission to the download destination folder. If your external hard drive is mounted at /external-hdd, then run the following command grant the qbittorrrent-nox user write permission to the download destination folder.

sudo setfacl -R -m "u:qbittorrent-nox:rwx" /external-hdd

In my opinion, using setfacl (set file access control list) rather than chown is a more flexible and better approach to manager permissions. setfacl will not change the ownership of a folder, it just grant permissions to additional users.

You may need to delete your torrent and re-add it after your run the setfacl command.

Accessing qBittorrent Web Interface Outside of Your Home Network

If you want to access qBittorrent Web UI remotely from your mobile phone or public Wi-fi, then you need to set up port forwarding in your router. Also I recommend setting up Nginx reverse proxy and enable HTTPS protocol to encrypt the communication.

Set Up Nginx Reverse Proxy for qBittorrent WebUI

reverse proxy is a proxy for another web server. In this case Nginx will be acting as the reverse proxy for the qBittorrent WebUI. Setting up Nginx reverse proxy makes it easy to enable HTTPS protocol.  Run the following command to install Nginx on Ubuntu 19.04.

sudo apt install nginx

Start Nginx.

sudo systemctl start nginx

Then create a Nginx server block file for qBittorrent WebUI.

sudo nano /etc/nginx/conf.d/qbittorrent-webui.conf

Copy and paste the following texts into the file. Replace the red-colored text with your own domain name. You should also set the A record for your domain name. If you don’t have a domain name yet, then I recommend buying domain name from Namecheap because their price is lower than GoDaddy and they give you whois privacy protection free of charge.

server {
  listen 80;

  access_log /var/log/nginx/;
  error_log /var/log/nginx/;

  location / {
    proxy_pass              http://localhost:8080/;
    proxy_set_header        X-Forwarded-Host        $server_name:$server_port;
    proxy_hide_header       Referer;
    proxy_hide_header       Origin;
    proxy_set_header        Referer                 '';
    proxy_set_header        Origin                  '';
    add_header              X-Frame-Options         "SAMEORIGIN";

Save and close the file. Then test Nginx configuration.

sudo nginx -t

If the test is successful, reload Nginx

sudo systemctl reload nginx

Now in your router, forward HTTP request (port 80) to the IP address of your Ubuntu server. After that, you can access qBittorrent WebUI via your domain name (

Note: If your ISP gives you a NAT-ed IP address, i.e. not a public IP address, then port forwarding won’t work. Instead, you need to use PageKite to expose local web server to the Internet.

Enable HTTPS to Encrypt Communications

To secure the Web UI, you can install a free TLS certificate issued by Let’s Encrypt. First you need to install the Let’s Encrypt client (certbot) on Ubuntu 19.04 server.

sudo apt install software-properties-common

sudo add-apt-repository ppa:certbot/certbot

sudo apt install certbot python3-certbot-nginx

Python3-certbot-nginx is the Certbot Nginx plugin. After they are installed, run the following command to automatically obtain and install Let’s Encrypt certificate.

sudo certbot --nginx --redirect --agree-tos --hsts --staple-ocsp --email your-email-address -d

Once that’s done, refresh the qBittorrent Web UI. It will be automatically redirected to HTTPS connection.
