[Sebastien Bacher]

I reproduced the bug on a fresh 20.04.6 install, just upgraded update-
manager, disconnected from internet and started update manager

Failed to connect to authentication server
Check your Internet connection and try again.

[info] A new version is available: 30~20.04
Please run:
    sudo apt-get install ubuntu-advantage-tools
to get the latest version with new features and bug fixes.

  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?
