Public bug reported:
It looks like mp in create_btrfs_root_snapshot in apt_btrfs_snapshot.py
is None.
Some Background information:
Some time ago, my hard drive broke, but I was able to recover all data
by copying it from the old file system. It looks like I've made a
mistake in the UUID of the file system: the UUID in /etc/fstab was not
equal to the UUID reported by gparted.
In the meantime, I've changed the UUID in /etc/fstab to the one reported
by gparted and my dist upgrade seems to run fine at the moment. Let's
hope, I'm able to boot after the upgrade ....
--------------------------
Here is the terminal output:
roughly translated as:
mount: Device .... does not exists.
Critical error occurred
Please create a bug report and add main.log and apt.log as attachment.
