When you have verified the correct signature on Release file you can go to next step – verifying the Packages file. Of course you'll need to verify the key in some other means (like the Debian/Ubuntu maintainers key, checking it from launchpad, etc, etc.) Gpg: There is no indication that the signature belongs to the owner. Gpg: WARNING: This key is not certified with a trusted signature! Gpg: Good signature from "Launchpad Datové schránky" Gpg: Signature made Fri 07:14:38 PM CET using RSA key ID F9C59A45 The next step would be to verify the signature on the Release file: $ gpg -verify Release.gpg Release You will have to click through the directories and find these files: wget
