VM won't start on Ubuntu 22.04

,

Hi
I am trying to setup an Ubuntu Virtual machine using LXD but the VM fails to boot and move beyond the boot screen. I think its an apparmor issue, but not sure. I’ve tried different versions of Ubuntu - 20.04, 22.04 but the result is the same.

During LXD installation, I see the following :

When I launch a new VM, I see the following:

Not sure what is going in and how to fix it. Any help will be greatly appreciated.

snap-confine suggests a snapd issue, perhaps a stuck refresh, have you tried restarting the snapd service or rebooting?

Thank you for the response @tomp . Yes, I’ve tried restarting and also reinstalling a couple of times. Is there another way to force a refresh?

What is the host OS?

Ubuntu 22.04
