Hints about enabling livepatch even if the service isn't available

[Steve Langasek]

After an upgrade from impish to jammy, update-manager rightly notifies me that livepatch should be available:

  The software on this computer is up to date.
  Tip: You can use Livepatch to keep your computer more secure between restarts.

However, when I click on the 'Settings & Livepatch' button to launch software-properties-gtk, after attaching a UA subscription to this machine (which I hadn't done previously), the Livepatch toggle is grayed out.

ua status says:

$ ua status
SERVICE ENTITLED STATUS DESCRIPTION
cc-eal yes n/a Common Criteria EAL2 Provisioning Packages
cis yes n/a Security compliance and audit tools
esm-infra yes n/a UA Infra: Extended Security Maintenance (ESM)
fips yes n/a NIST-certified core packages
fips-updates yes n/a NIST-certified core packages with priority security updates
livepatch yes n/a Canonical Livepatch service

Enable services with: ua enable <service>

     Account: <email address hidden>
Subscription: <email address hidden>
$

Running 'sudo ua enable livepatch' reports:

Livepatch is not available for Ubuntu 22.04 (Jammy Jellyfish).

So perhaps this is an issue of update-manager only checking that we're on an LTS, rather than checking that the livepatch service is available from the server? But, that also means connectivity issues could result in the user never being prompted to enable livepatch.

When is livepatch going to be available for 22.04 LTS?

The toggle being greyed out is wanted since the service is not available but maybe the UI could reflect better when it's disabled?

Reassigning to update-manager though since the main issue is that the hint displayed is invalid.

It's probably low importance once livepatch is available
