Problema with signed-by zorin 18

Neo1 · March 11, 2026, 2:37pm

Hello. A few days ago I updated to Zorin OS 18 from Zorin 17, but when I try to update I get this error:
N: Hace falta «Signed-By» en la entrada sources.list(5) para «https://packages.zorinos.com/stable»
N: Hace falta «Signed-By» en la entrada sources.list(5) para «https://packages.zorinos.com/patches»

N: Hace falta «Signed-By» en la entrada sources.list(5) para «https://packages.zorinos.com/drivers»
Could you help me fix this? Thanks!

Okay, I have found something. Your Key differs from mine up here:

Let's check something: When You go to Software & Updates and there the first Tab. Is the Download Source set to ''Main Server''?

Neo1 · March 12, 2026, 6:30pm

No, I have it on a server for Spain.

Neo1 · March 12, 2026, 6:36pm

I've changed it to the main server, but I'm getting the same error.

You are not the first user to note that the Zorin Upgrader Tool is not properly migrating the Zorin OS repository signature.
I would need to search for it, but a recent thread covered this same issue, too.

I think this must be reviewed by the ZorinGroup directly, so will reference this thread.

Ponce-De-Leon · March 13, 2026, 11:35am

Okay, it seems that You have to add for now manually the right Key to these Files. Fortunately, You need the same Key for all 4. So, what You now have to do is, open the Terminal and type:

sudo nano /etc/apt/sources.list.d/zorinos-ubuntu-apps-noble.sources

and there delete Your Stuff in it and copy this into it:
