Hello, and sorry for the late reply here. If by any chance you still have access to the system, would you be able to show the output of running 'ls -l /var/lib/snapd/hostfs' in the terminal? The dpkg terminal log included with you bug report says it's not owned by root, and I'm curious as to who the owner is and perhaps why it happened.
