a user just had the "snapd always hanging on install/reinstall and blocking apt" issue.
after some fiddeling we used the workaround from Comment#4 https://bugs.launchpad.net/ubuntu/+source/snapd/+bug/1621336/comments/4 :
starting a rootshell with "sudo -i". then running "echo "bash -c 'service snapd.boot-ok start'" | at now + 4 min", then "apt install snapd" (if it argues about canceled dpkg processes use the "dpkg --configure -a". then wait for at least 4 minutes.
the hanging should gone then.
