Comment 9 for bug 1841137

So, I thought this bug had disappeared, as I haven't seen it for a long time.

After upgrading to focal, now I see this happening again.
I have two drives in Gnome file manager, which match these:

$ losetup | grep del
/dev/loop13 0 0 1 1 /var/lib/snapd/snaps/lxd_13717.snap (deleted) 0 512
/dev/loop31 0 0 1 1 /var/lib/snapd/snaps/lxd_13704.snap (deleted) 0 512

These files no longer exist.

As before, `losetup -d` is not effective.
