I also had to boot into a rescue disk to completely remove Snap from my system.

I also found traces of Snap in /etc after removal. Apt and the
uninstaller leaves a bunch of systemd units lying around. I used
`find` to locate them and delete them. Something like:

    find /etc -name '*snap*' -exec rm -f {} \;

Once you remove the systemd units, you won't get those mounts and you
should be able to delete Snap files and directories without error.
