FAQ
Is there a GitHub Desktop for Linux?
Yes — while GitHub doesn't publish an official Linux build, this actively-maintained open-source fork provides one, installable via a signed apt repository or direct .rpm / AppImage downloads.
Is it safe / trustworthy?
The APT repository is GPG-signed, so apt verifies every package. It's MIT-licensed open source; the code is on GitHub. It is an unofficial community build, not affiliated with GitHub, Inc.
Does it update automatically?
On Ubuntu/Debian, yes — updates come through your normal apt upgrade.
