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

    Run sudo apt install gtk3-nocsd and then export LD_PRELOAD=/usr/lib/x86_64-linux-gnu/libgtk3-nocsd.so.0. Also, canonical-livepatch refresh require sudo privileges – Kulfy May 12 '19 at 12:04

In terminal i just fire this command and it worked, try this

sudo canonical-livepatch refresh

In Detail you can read here

    I started to receive error after manual update and restart of computer (restart was required even before livepatch was activated on the machine). This one helped. Thx, – Honza P. Feb 11 at 20:28

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>

  • I started getting this after cloning to a new SSD. Getting a new token fixed it. – aucuparia Jan 5 at 8:15
  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

  • Welcome to Ask Ubuntu! According to the question, OP had livepatch set up already but got a problem with it. Your answer is not even trying to solve this problem. – Melebius Jun 18 '19 at 11:34
