Thank you again for figuring this one out!

ubuntu-advantage-tools?

I can't think of anything either other than a manual 'apt udpate; apt
install update-manager'.

valid json output, either by catching the exception or by backporting
the switch to use the proper python api

If it is indifferent, then I'm going with the latter since we already
did it for 24.04. The documentation says it raises no exceptions[1].

I'll open the merge request once I have it tested.

  Is it the ubuntu-advantage-tools version problem, is it the failure to
  access contracts.canonical.com? Should we switch to calling the API
  directly as in 24.04[1] or handle the exception?
