Livepatch has fixed kernel vulnerabilities. Or not???

[Bo Berglund]

I saw this yesterday when I logged on via SSH to my Ubuntu Server 20.04.6 LTS:

*** Livepatch has fixed kernel vulnerabilities. System restart recommended on
the closest maintenance window ***

Today was the possible "maintenance window" so I rebooted the server.

Now when I log on *after* the reboot I see this greeting:

What gives?
Do I have to do multiple reboots to get this done, if so why?
Otherwise: What should I do now?
