It is now moving on to the main article on installing the BitTorrent software.

Method 1: Install qBittorrent Desktop

In this section, we delve into installing the qBittorrent desktop client on your Debian system and initializing it for the first time. It is essential to keep your system up to date to avoid conflicts and ensure compatibility with the qBittorrent installation.

Update Debian Before qBittorrent Installation.

Updating the system package list and upgrading the installed packages ensures that you work with the latest software by running the following command:

sudo apt update
sudo apt upgrade

If the upgrade involves updating many packages or the Linux kernel, it is wise to reboot the system for the changes to take effect.

sudo reboot

Install qBittorrent Desktop via APT Command

With an updated system, you are set to install qBittorrent. This versatile desktop client can be installed directly from Debian repositories. Execute the following command to install qBittorrent:

sudo apt install qbittorrent

This command will retrieve the latest qBittorrent package from the Debian repositories and install it on your system.

Launch qBittorrent Desktop Client

With qBittorrent successfully installed, it is time to launch the application. You can do this from the terminal by executing:

qbittorrent

This launches the qBittorrent client, and you are now ready to manage your torrents.

You can launch qBittorrent from your system’s application menu if you prefer graphical interfaces. To do this, follow these steps:

Activities > Show Applications > qBittorrent

Read Legal Notice From qBittorrent

A legal notice will appear when you launch qBittorrent for the first time. This notice helps protect qBittorrent from legal issues related to torrent sharing. After you agree to the notice, the main window of qBittorrent will open, and you can start using the software.

Method 2: Install qBittorrent-nox (server / web-UI)

In this section, we focus on installing qBittorrent-nox, which is particularly beneficial for running qBittorrent on a headless Debian server or remotely accessed desktop. The WebUI interface enables efficient management of qBittorrent via a web browser.

Install qBittorrent-nox via APT Command

Begin by installing qBittorrent-nox with the command below. It’s tailored for headless systems, and the Web interface can be accessed at the default location http://localhost:8080.

sudo apt install qbittorrent-nox

Create a Dedicated System User and Group for qBittorrent

For enhanced security, qBittorrent-nox should run as an unprivileged user. Creating a systemd service unit facilitates this, as it operates in the background and initializes at system boot.

Execute the following command to create a user and group for qBittorrent-nox:

sudo adduser --system --group qbittorrent-nox

The --system flag specifies that this is a system user, which doesn’t have the full capabilities of a regular user.

Add Your Username to the qBittorrent-nox Group

To grant your user account the necessary permissions, add it to the qbittorrent-nox group:

sudo adduser your-username qbittorrent-nox

Replace your-username with your actual username.

Create a Systemd Service File for qBittorrent-nox

Create a new systemd service file to define how the qBittorrent-nox service should run:

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

Enter the following content 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

Save and close the file by pressing CTRL+O followed by CTRL+X.

Reload the Systemd Daemon

To activate the new service, reload the systemd daemon:

sudo systemctl daemon-reload

Start and Enable qBittorrent-nox

Now, start the qBittorrent-nox service and enable it to start on boot:

sudo systemctl start qbittorrent-nox
sudo systemctl enable qbittorrent-nox

sudo systemctl enable qbittorrent-nox

It’s a good practice to check the status to ensure the service is running smoothly:

systemctl status qbittorrent-nox

If you find an error, the most common issue is the qbittorrent-nox service cannot create the required directories. To fix this, run the following commands:

sudo mkdir /home/qbittorrent-nox
sudo chown qbittorrent-nox:qbittorrent-nox /home/qbittorrent-nox
sudo usermod -d /home/qbittorrent-nox qbittorrent-nox

Then start or restart the service:

sudo systemctl start qbittorrent-nox

Access qBittorrent Web UI

Access the qBittorrent Web UI through a browser by entering your server’s internal IP address followed by the port number (8080), like 192.168.55.156:8080. If running locally, use 127.0.0.1:8080.

Remember, the default username is admin, and the password is adminadmin.

It’s paramount to change the default login credentials for security purposes. Navigate through Tools > Options > Web UI > Authentication in the Web UI. Here, you can set a custom username and password.

This step ensures that your qBittorrent Web UI is secure and accessible only to individuals with the proper credentials.
