How to Install qBittorrent on Debian 11 Bullseye

qBittorrent is a cross-platform free and open-source BitTorrent client. qBittorrent is a native application written in C++ which uses Boost, Qt 5 toolkit, and libtorrent-rasterbar library and is extremely lightweight and fast. qBittorrent is very popular amongst torrent users as the main alternative to UTorrent.

In the following tutorial, you will learn how to install qBittorrent on Debian 11 Bullseye desktop GUI and install qBittorrent-nox, which can be installed on a desktop or headless server using the command line terminal to access the WEB UI.

Update Debian

First, before anything, update your system to ensure all existing packages are up to date.

sudo apt update && sudo apt upgrade -y

Install qBittorrent-nox – Server Method

qBittorrent can be installed on a desktop that will be accessed remotely or headless Debian servers and efficiently managed on a WebUI interface accessed from your favorite Browser.

Import qBittorrent-nox Stable (Recommended)

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

Import qBittorrent-nox Unstable (Nightly)

sudo add-apt-repository ppa:qbittorrent-team/qbittorrent-unstable -y

Next, run a quick APT update to reflect the newly added PPA.

sudo apt update

Now you can install qBittorrent using the following command.

sudo apt install qbittorrent-nox -y

qBittorrent-nox is the default go-to for headless clients designed to run through a Web interface accessible on the default localhost location at http://localhost:8080. The Web UI access is secured by default, the default account username is (admin), and the password is (adminadmin).

Unlike the desktop version, using the terminal command (qbittorrent-nox) would not be advised as a headless server; you won’t be able to do anything while qBittorrent is running, which isn’t practical. Instead, you will create a systemd service unit to run in the background and start at system boot.

First, create (qbittorrent-nox) user and group so the service can run as an unprivileged user.

sudo adduser --system --group qbittorrent-nox

If you were wondering what (–system) means, you created a system user instead of a typical user.

Next, add your username to the qbittorrent-nox user group.

sudo adduser your-username qbittorrent-nox

Example using my username:

sudo adduser joshua qbittorrent-nox

Example output:

Second, create a systemd service file for qbittorrent-nox.

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

Thirdly, you must copy and paste the following lines into the file.

[Unit]
Description=qBittorrent Command Line Client
After=network.target

[Service]
Type=forking
User=qbittorrent-nox
Group=qbittorrent-nox
UMask=007
ExecStart=/usr/bin/qbittorrent-nox -d --webui-port=8080
Restart=on-failure

[Install]
WantedBy=multi-user.target

Example:

How to Install qBittorrent on Debian 11 Bullseye

Save the file (CTRL+O), then exit (CTRL+X). Now, reload your systemd daemon for changes to be active with the daemon-reload command.

sudo systemctl daemon-reload

Now you can start qBittorrent-nox with the following command.

sudo systemctl start qbittorrent-nox

If you want qBittorrent-nox to be started automatically on boot, use the following.

sudo systemctl enable qbittorrent-nox

Before you continue, it would be ideal for checking the status to ensure everything is working correctly.

systemctl status qbittorrent-nox

If there are no errors and status in the green, proceed to the next part of the tutorial.
