Okay, thank you. The next Step. We need to control the Files that mentioned in the Warning Messages.
Open Nautilus (the File Manager), go to ''Other Places'' at the bottom Left, then click on the right on Your Drive and go to /etc/apt/sources.list.d/ and look for the Files zorinos-ubuntu-patches-noble.sources and zorinos-ubuntu-stable-noble.sources and open them with Text Editor and post the Output of the Files here please.
Okay, I see directly that on both stands stable in the URI Line. The next Problem: My Adresses are different that Yours. And the Signed-By Line is wrong.
Okay, when You go to Software & Updates and there the first Tab. Are the Souce Option is set to ''Main Server''? If not, switch and then try it again.
