Strange. I notice that the number of reviews for Krita changes between the before and after screenshots, too. It looks like a backend might have stopped working or something. Do you have multiple backends installed?

Use the information offered by the transaction instead of clearing the
package and resolving the packages again. PackageKit apt backend is
