snapper rollback does not work on ubuntu for btrfs

[GreyGeek]

It's been two or three years since I've used snapper. Apparently it has lost some compatibility with the way Kubuntu uses @.

snapper rollback for root volumes have no effect. After calling snapper rollback, the default is being set correctly as seen via btrfs subvolume get-default. However, ubuntu doesn't seem to boot into that snapshot.

It was first reported on Dec 11, 2017 and the most recent report is June 18, 2018.

Until that is fixed the best Btrfs backup GUI appears to fall to TImeshift.
