In Detail you can read here

1. Canonical Livepatch informs about internal error - what to do?
2. https://ubuntuforums.org/showthread.php?t=2420465

This forum thread describes the same issue and says the solution is to use a new livepatch token:

1. disable the livepatch service sudo canonical-livepatch disable

2. get a new token from https://auth.livepatch.canonical.com/

3. enable the service with your new token sudo canonical-livepatch enable <your token>
