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 perform 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. You can change the update channel in the system settings under the "Aurora Preferences" category.
Rolling back bad system upgrades
If a 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
:stableupdate channel.
Use the rebase-helper tool to rebase for the following reasons:
- Switching to an older Aurora build temporarily
- Swapping to a different update channel
- Hardware changes that require switching to or moving away from a hardware specific image (like an image preinstalled with Nvidia drivers)
