How to Install qBittorrent in Ubuntu Linux

The software provides official Linux package through .AppImage package, available to download the link below:

It’s a non-install package, that can be run directly to launch the torrent client. Just right-click on .AppImage file and go to ‘Properties’, then enable “Allow executing as program” option under Permissions tab. Finally, click run it to launch the app.

For choices, you can also install qBittorrent 4.6.0 through Flatpak and Ubuntu PPA.

```
sudo apt install flatpak
```

Then, install the torrent client as Flatpak by running command:

flatpak install https://dl.flathub.org/repo/appstream/org.qbittorrent.qBittorrent.flatpakref

Option 3: Ubuntu PPA

UPDATE: Due to requirement of Qt > 6.5.0, the PPA will NOT update for Ubuntu 24.04, Ubuntu 22.04 and earlier.

For those who prefer the native .deb package format, qBittorrent has an official Ubuntu PPA. Though, it’s NOT updated at the moment of writing (check the previous link).

sudo apt update
```
