after running omv-release-upgrade from 5.6.20 to OMV 6.x (RC1), I solved varius issues and the system is on.
Now I have a problem to solve: the plugin are still on 5.x.
I manually removed all .deb plugins and purged.
I also have removed and purged openmediavault-omvextrasorg but nothing is changed (see attached img).
At least I tried to reinstall (apt reinstall openmediavault), but nothing.
What I can do now?
1) I also have a OS full backup done before the upgrade (clonezilla) so I can re-run the omv-release-upgrade.
2) I can describe to volker (or others) issues I already solved (#1 not existing salt modules Error that interrupted migration and #2 wrong path of mount in /etc/monit/conf.d)
