[15.3 retro] A openQA test to check published package's installability

[nilxam]

When a new build was testing in openQA, we should have a test to run libsolv against the synced asset repository in openQA in order to find uninstallable package before we publish the new build to pontifex. Instead of libsolv, try to install all package from asset repo is another option.

Damage Uninstallable package does exist in ftp

Solution Executing libsolv against the asset repository in openQA to find those uninstallable package in ftp

Action item here is to create a task in progress-o-o for openQA. Once it is there, we no longer need to have it the release checklist.
