Snap
Note that snaps are going to be removed from Solus in the future, and are not fully confined in Solus with Linux 6.9 and newer. See the section on confinement below.
Snaps are a way of installing third-party packages.
The snapd package installs the CLI client that can be used to install and run snaps.
Confinement warning
Snaps are usually protected using strict confinement,
ensuring that snaps can't access more of your system than needed.
The snap command provided by Solus shows a warning when strict confinement is not available.
For example:
WARNING: snap is running with partial confinement. See https://help.getsol.us/docs/user/software/third-party/snap for details
We recommend migrating to Flatpak when possible.
The warning can be silenced by running sudo snap hide-confinement-warning.
Migrating to Flatpak
The unsnap package can be used to migrate from snap to Flatpak.
While it does not actively remove user data in ~/snap or /var/lib/snapd,
we cannot guarantee that no data gets removed on accident.
Please ensure you have system backups that include snap data.
Run sudo unsnap before migrating to see if all your snaps have known equivalents.
Look for lines containing No equivalent flatpak for <name> found.
Check out this issue if you encounter such snaps.
Running sudo unsnap auto will migrate as many snaps to Flatpak as possible.
It will also uninstall snapd if all snaps were migrated.
If unsnap is unable to find an equivalent Flatpak for a snap, you have the following options:
- Search for an equivalent Flatpak manually, and report it if possible.
- Install an equivalent tool from the package manager if possible.
- Uninstall the snap manually if it is not needed.
It is possible to rerun sudo unsnap auto to finish removing snapd.
