Managing Repositories with Repoman

Repoman allows users to add apt and Flatpak repositories. Users may want to add an apt repository or additional Flatpak repository if their software is not included in the Pop!_Shop, or they may want to remove an unneeded repository after uninstalling the only application that required it.

Access Repoman by launching the Pop!_Shop, clicking the three lines, and then clicking System Software Sources....

Access Repoman

Caution: Adding third-party apt or Flatpak repositories allows installation of software that has not been validated by System76 or other trusted Linux communities. Software available via third-party apt and Flatpak repositories may not be vetted against packages that introduce security vulnerabilities. Users should take caution and only add external repositories that they trust.

Official Sources

This section lists System76's Ubuntu mirror. This mirror includes Pop!_OS application packages that come from Ubuntu (additional packages that make Pop!_OS are added on top via the apt.pop-os.org/release repo found in the Extra Sources tab). This is also where installation files for many applications in the Pop!_Shop reside. Changing this mirror is not necessary since Pop!_OS will automatically download updates from the fastest source using System76's worldwide CDN.

The toggle switches enable or disable software components based on licensing and support:

Restricted - Proprietary drivers and components that are not open source
Universe - Free and open-source software that is community maintained
Multiverse - Software restricted by copyright or legal reasons
