Comment 5 for bug 1880156

@xnox I was using the beta channels, probably with a custom built image.

> I'm confused how a refresh of core20 can do anything.

A refresh of core20 will cause snapd to stop responding to it's REST API until it has rebooted, causing console-conf to hang trying to run `snap create-user`

> Can snapd, refresh snapd.snap without reboot?

Yes the snapd snap can be refreshed without a reboot.

> Do you have logs from that system? Ie. all the snapd changes?

Not anymore but this is pretty easily reproduced if you just build an image with the beta core20 snap as a revision older than what's currently on the beta channel.

> Can we inhibit / pause refreshes and reboots, if somebody launched consoleconf?

Sort of, see https://snapcraft.io/docs/system-options#heading--refresh specifically refresh.hold key. Note that setting this key is slightly buggy though as per https://bugs.launchpad.net/snapd/+bug/1856063
