Comment 2 for bug 1876979

I have chosen the LXD '4.0' realease path

As the 'do-release-upgrade' will break in the middle on the upgrade process I fix the upgrading myself with this steps:

1) sudo apt purge lxd-client lxd

2) sudo apt update && sudo apt dist-upgrade

afterward lxd runs as expected from snap
