[Bug 1833277] Re: LIvepatch widget should link to secure boot information on error

[Steve Langasek]

Very good feedback.  Letting the user know that the livepatch failed to
apply is a good first step, but I agree that the interface should guide
the user in how to resolve the issue.

Title:
  LIvepatch widget should link to secure boot information on error

Status in update-notifier package in Ubuntu:
  Triaged

Bug description:
  The livepatch widget will show an error[0] if patches cannot be
  applied. They cannot be applied on a Secure Boot system unless the
  livepatch signing key is imported. Unfortunately this requires a
  reboot and some confirmation in the UEFI settings, so it can't be
  automated.

  `canonical-livepatch help` displays some instructions to fix this:

  
  SECUREBOOT:
         If you are using secure boot, you will also need to import the livepatch public keys into your keyring.

         This can be done with the following command:
         sudo mokutil --import /snap/canonical-livepatch/current/keys/livepatch-kmod.x509

         After this enter a password if necessary for MOK, then reboot.
         Your BIOS will then guide you through enrolling a new key in MOK.
         At this point you will be able to verify the module signatures.

  This is probably something worth linking to from that error message.
  In general, we might need a page explaining other reasons the kernel
  can't be patched, how to get more details from the system log, etc.
