Hello Gene Sun, thank you for taking the time to file a bug!

The livepatch service is installed as a snap when you run `ua enable livepatch`. It looks like the `snap` command is failing because the snapd.socket isn't available.

Can you verify that the snap service is working or not by running a snap command like `snap services`?

Here is what I saw. (I had reinstalled snap)

Hello Gene Sun,

It seems there is something wrong if your snapd service.
What is the output of running:

$ systemctl status snapd

And if the service is not running, can you run:

$ systemctl start snapd.service

And double check if snap services is now running as expected ?

Hi Gene Sun,

This is a really odd issue and I have never experienced it before. I think the best path forward is to contact the snapd team and ask for help there, as this could be a bug on the package:
https://bugs.launchpad.net/ubuntu/+source/snapd

Since this is issue is snapd related, I am closing this issue for now. But if you are able to sort the snapd issue and livepatch still fails, please contact us again and we will more than glad to help you with that.
