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. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1621336 Title: snapd.boot-ok.service hangs eternally on cloud image upgrades To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/cloud-init/+bug/1621336/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
