Comment 66 for bug 1990450

Ran my 20.04.06 virtual machine.

Updated ubuntu-advange-tools, installed hello package (as it is listed in https://esm.ubuntu.com/apps/ubuntu/dists/jammy-apps-security/main/binary-amd64/Packages), enabled proposed in software-properties-gtk, installed update-manager .17.

Ran update-manager, got pro security updates section and hello in there, insensitive as machine not attached.

Clicked Settings... to invoke software-properties-gtk, went to Ubuntu Pro section and attached the machine.

Upon successful attachment, closed the software-properties window, update-manager recalculated and now the update of hello package was available (sensitive button).

Step 6 didn't work right away, but that is because it takes something for ua daemon to kick up, you can give it a hand with

  find /var/lib/apt -name '*stamp' -ok rm {} \;
  systemctl start apt-news

and then the section will show.
