How did you get 3.5.4 on Focal? But besides that, differences between the two versions are marginal. In particular, the actual Python code ( /usr/lib/python3/dist-packages/apt_btrfs_snapshot.py ) didn't change at all.
I did some further testing. Right now, # apt-btrfs-snapshot list-older-than 1d also works on my system. What doesn't work however, is any interval greater than 1d: 2d, 3d, 4d, 30d, 90d, … In all these cases an empty list is returned (at the moment right now). What makes things even more strange: Scrolling back in same terminal window to what I've tried just a few hours ago, I have clear evidence, that the very same command # apt-btrfs-snapshot list-older-than 1d did return only two snapshots, one taken a bit less than 24 h ago, the other slightly older, omitting many other snapshots. I have no clue what caused this change. (No updates or other changes to any installed packages have been made between the two scenarios.) -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1322838 Title: delete-older-than destroys inappropriate snapshots To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/apt-btrfs-snapshot/+bug/1322838/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
