Managing Installed Applications

Flatseal

Manage Flatpak permissions thoroughly. KDE Plasma’s system settings can also change permissions, but not as granular.

Warehouse

Manage installed Flatpaks by downgrading, backing up user data, and adding additional Flatpak remotes.

Pre-Installed Aurora Packages

Unfortunately, due to a limitation with OCI images, there are too many downsides to recommend uninstalling the pre-installed packages that ship with Aurora without forking the project, building your own based on our template, or using the unaffiliated Blue-Build project.

These downsides include:

• Longer upgrades times
• More storage will be used despite the package being removed

Using ujust in Aurora

ujust is a set of scripts by Universal Blue maintainers and contributors that can do the following actions:

• Installing specific software
• Managing the system and maintenance

View the entire list of ujust commands by entering this terminal command:

Updates

System updates and applications are automatically updated on a daily schedule.

Rolling back bad system upgrades

If a bad regression occurs during a system update, then you can rollback to the last deployment…

rpm-ostree rollback

Rebasing to specific Aurora images

Note: System updates are paused when you rebase to an older image until you rebase back to :stable

Use the rebase-helper tool for a specific image.
