QQ for Linux is Back, 10 Years After Discontinued!

Last updated: January 9, 2023

Tencent QQ, one of the most favorite instant messaging apps for Chinese users, now is back to Linux. And, it’s now in 3.0 release.

QQ for Linux was discontinued about 10 years ago. Now it’s back with following features:

Support x64、ARM64.
Offers .rpm, .deb for Fedora, Debian/Ubuntu, and AppImage package for most Linux.
Login by scanning QR Code via QQ on mobile.
Send texts, files, pictures, and take screenshots.

At the moment it’s QQ Linux 3.0 with modern UI powered by Tencent’s own QQNT framework. Which, is working perfectly in my case except for the video/audio chat support.

QQ for Linux 3.0

If you’re looking for QQ Linux package with full (or most) functionality, I’d recommend Deepin Wine QQ, or community build QQ Flatpak package.

To get the new QQ for Linux client, just go to its official website via the link button below:

Download QQ for Linux

Then, simply double-click the package to install it via Ubuntu Software and enjoy!

(Optional) To remove the IM, simply open terminal (Ctrl+Alt+T) and run command:
