livepatch snap breaks "snap services" output

[Dave Havlicek]

Before enabling livepatch:

> snap services
Service Startup Current Notes
certbot.renew disabled inactive -

After enabling livepatch:

> snap services
error: cannot get status of services of app "canonical-livepatchd": cannot get unit status: bad
       line "Bus n/a: changing state UNSET → OPENING" in ‘systemctl show’ output

Nothing else about livepatch seems to be failing. The kernel does get patched periodically with no apparent problems. The output of "systemctl show" is attached as well as the other commands.

This looks to be a snapd issue.

This is a duplicate of 1885597, the issue is that snapd isn't smart enough to ignore the extra debug output from systemctl when systemd's debugging is turned on.
