This isn't a gdm3 bug, right? If it's a systemd or systemd unit problem and it's still happening, we probably need to provide some more information so that xnox or someone can help and take a look. I tried and just booting a live session in a VM and shutting it down works for me.
Can someone give clear reproduction steps, preferably for making this happen in a VM? If it only happens for some people for some reason, maybe an affected person can get a journal log for this bug report: https://freedesktop.org/wiki/Software/systemd/Debugging/#index2h1 - although it'll be a bit harder to get it out of the live session it should be possible e.g. to mount a hard drive or a USB key or a 9p shared volume using virt-manager (hopefully that last one works at late shutdown). ** Changed in: gdm3 (Ubuntu Bionic) Status: Confirmed => Incomplete -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to systemd in Ubuntu. https://bugs.launchpad.net/bugs/1706939 Title: A live session can't be shut down due to "[ *** ] (2 of 2) A start job is running for ...
