when I open Ubuntu Software in the Updates panel I see "core 22 20230725", but when I click update I got the message in the title.
The exact message I got is: "Impossibile aggiornare core 22: snap has no updates available", because it's in Italian, so I don't know exaclty which is the message in English.
I've tried "sudo apt update && sudo apt upgrade", which worked correctly but did not change the situation.
I've Ubuntu 22.04
Thanks for any suggestion
