I installed few weeks ago gnome-software to use instead of appcenter, because this one didn't work for me - it didn't update any package. Gnome-software did work fine until a couple of days ago, after OS updates it crashed and couldn't find it anymore in my installed apps.
I tried and reinstall it with no success:
I seguenti pacchetti hanno dipendenze non soddisfatte: gnome-software : Dipende: appstream ma non sta per essere installato E: Impossibile correggere i problemi, ci sono pacchetti danneggiati bloccati.
which means that there's a problem with damaged or blocked packages (appstream). But this package is correctly installed:
Package: appstream Status: install ok installed
Thank you for any help.
