Following the instructions here: MicroK8s - MicroK8s in LXD . My Ubuntu desktop sessions logs off and when I log back in session has restarted. The profile from that page is reproduced below check to see if some configuration is problematic there.
### This is a YAML representation of the profile.
### Any line starting with a '# will be ignored.
###
### A profile consists of a set of configuration items followed by a set of
### devices.
###
### An example would look like:
### name: onenic
### config:
### raw.lxc: lxc.aa_profile=unconfined
### devices:
### eth0:
### nictype: bridged
### parent: lxdbr0
### type: nic
###
### Note that the name is shown but cannot be changed

I have an other instance that doesn’t use this profile and it doesn’t suffer this issue when stopping and starting it.
