Canonical Livepatch has experienced an internal error, on start up
sudo canonical-livepatch refresh
does that fix it for the current session?
If so and it does not work anymore after a reboot you might want to add this to a cron with an @reboot. The message comes from their server so it might be an issue on that end and not with your machine.
You need to file a bug report if your kernel is supported by livepatch. This
no livepatches needed for this kernel yet
would suggest it is not.
You are not the only one with issues in the past few hours
