Logging in by ssh - last line - is anything wrong?

[David Fletcher]

I've been seeing this:-

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

for the last couple of days, when logging in by ssh to my home server
running Ubuntu 20.04.6 LTS server, headless. System is updated and
restarted but I still get the warning.

I have another system, running Ubuntu 22.04.2 LTS server, headless, on
an identical motherboard but connected by WiFi and installed on my
first ever SSD. This one doesn't output the above warning message.

Both systems are running on static IPv4+IPv6 addresses.

Should I be concerned about the warning message? Or is it a glitch that
will eventually go away by itself?

Thanks for reading and hopefully for some advice from those more
knowledgeable than myself.
