Test plan for update-manager

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

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.

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.
