So far there is no good tooling to move the flatpaks installed with the defaults from system to user. I did not want to go through them manually, so wrote a bash script
Before:
knurpht@Lenovo-P16:~> LANG=C flatpak --system list
Name Application ID Version Branch
Mesa org.freedesktop.Platform.GL.default 25.3.5 25.08
Mesa (Extra) org.freedesktop.Platform.GL.default 25.3.5 25.08-extra
Codecs Extra Extension org.freedesktop.Platform.codecs-extra 25.08-extra
Adwaita theme org.kde.KStyle.Adwaita 6.10
KDE Application Platform org.kde.Platform 6.10
Amarok org.kde.amarok 3.3.2 stable
knurpht@Lenovo-P16:~>
knurpht@Lenovo-P16:~> LANG=C flatpak --user list | grep -i amarok
knurpht@Lenovo-P16:~>
knurpht@Lenovo-P16:~> LANG=C flatpak --user remotes
knurpht@Lenovo-P16:~>
This shows that Amarok is installed as system flatpak, not installed as user flatpak, and that the user has no remote installed. This comes from my real system where I aleady ran the script before, so the rest of the flatpaks are already gone to the user.
