I have this problem since I installed Ubuntu few weeks ago. I read through few similar post and none was exactly they way I experience a problem.
Very frequently (50% of days) when I turn on my PC and login to Ubuntu there is a Livepatch error saying "An error occurred while checking for livepatch updates".
I check status page of Cannoncial services - all operable. I tried to diable Livepatch in Software Updates Settings, but it gave me an error, something about not being able to disable Livepatch, but the switch for Livepatch setting went into "off" position and Livepatch icon disappeared from taskbar. So after googling I enabled it with sudo pro enable livepatch - SUCCESS. Then I checked the status with canonical-livepatch status --verbose and got following result:
:~$ canonical-livepatch status --verbose

I tried to disable and re-enable Livepatch again right away. Diable through GUI went with the same effect - "cannot disable livepatch". Then I tried via console sudo pro disable livepatch and got this:
Livepatch is not currently enabled - nothing to do.
See: sudo pro status
So I checked pro status with sudo pro status and got
SERVICE ENTITLED STATUS DESCRIPTION
anbox-cloud yes disabled Scalable Android in the cloud
esm-apps yes enabled Expanded Security Maintenance for Applications
esm-infra yes enabled Expanded Security Maintenance for Infrastructure
landscape yes disabled Management and administration tool for Ubuntu
livepatch yes disabled Canonical Livepatch service
realtime-kernel* yes disabled Ubuntu kernel with PREEMPT_RT patches integrated
Then I tried enabling Livepatch again with sudo pro enable livepatch, but this time it didn't let me:

I tried again with different error:

Could not enable Livepatch.
I don't know what to do next, it feels so random that it works half of the time when I use PC and half it does not... Anything I could ran to debug/solve the problem?
PS. 5 minutes later I did sudo pro enable livepatch and it was successful with errors...
