Update Manager test plan

  1. If apt list --upgradable returns nothing, downgrade a package in the system.

    Tip

    Of course it’s better to do so with a cosmetic package that has no chance to impact the system, e.g. cowsay.

  2. Start update-manager.

  3. Verify that update-manager suggests packages matching the output of apt list --upgradable.

    Note

    If the list is too long, just scanning over the output is OK, as Apt will list package names and Update Manager their short descriptions and that makes a one-by-one comparison very slow.

  4. Install one or more updates via Update Manager, verify that the corresponding packages are gone from

    • apt list --upgrade; and

    • update-manager’s recalculated view.
