Public bug reported:
A Docker container, like an LXD container (bug 1759257), cannot load
kernel modules, so it should not report Canonical Livepatch as being
available in the motd.
$ docker run --rm -it ubuntu:18.04
root@12d1934cc2df:/# apt-get update
root@12d1934cc2df:/# apt-get install lsb-release ubuntu-advantage-tools
root@12d1934cc2df:/# /etc/cron.daily/ubuntu-advantage-tools
root@12d1934cc2df:/# /etc/update-motd.d/80-livepatch
* Canonical Livepatch is available for installation.
- Reduce system reboots and improve kernel security. Activate at:
