I've started seeing a livepatch warning in my system tray.

System tray icons.

Clicking it takes me the the livepatch client where I see this error message:

Canonical Livepatch has experienced an internal error. Please refer to https://wiki.ubuntu.com/Kernel/Livepatch#CommonIssues for further information.

Despite the URL, there isn't a #CommonIssues section on the page: https://wiki.ubuntu.com/Kernel/Livepatch#CommonIssues

Any ideas how I can fix this?

Ubuntu 18.04.2 LTS
4.15.0-34-generic

First of all what is connonical-livepatch, its a service provided by ubuntu for critical infrastructure ( which your desktop is not ) to remove the code that might be harmful, without requiring an restart. I dont think a desktop needs it, so disable it.

Secondly if you are not using Ubuntu Pro ( Its part of Pro, you need to create an account, and make sure token is there ) , I dont think it will work anyway, thats why you get error because you dont have token for getting those.

If you are actually running some critical infrastructure, then getting on not getting is up to you

For most users using ubuntu in desktop simply disable it.

but if you are still using it, and you know that you have the token maybe give it a refresh, maybe there is some error in network etc.

Note: Some people have found simply running sudo canonical-livepatch refresh solves the problem. Try that first and then, if the problem persists, follow the steps below.

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>

  4. restart livepatch service

    sudo systemctl restart snap.canonical-livepatch.canonical-livepatchd.service

I tried the other methods, but had to remove the lock file for some reason and restart the service.

s=snap.canonical-livepatch.canonical-livepatchd.service; sudo rm /var/snap/canonical-livepatch/common/locks/livepatch_Ubuntu_5_15_0_71_78_generic_95_95.4 && sudo systemctl restart && sudo systemctl status

  1. head to the Livepatch page and create an account. You can license up to 3 servers for free, so there is no cost unless you plan to mass deploy Livepatch. https://www.ubuntu.com/server/livepatch

  2. Once you've created an account it's as simple as running the following commands:

    sudo snap install canonical-livepatch  
sudo canonical-livepatch enable $your_token
