Failed to parse PKI

Fedora Linux 42 (Workstation Edition). Linux 6.16.7-200.fc42.x86_64

I can’t update. It gives messages: sudo dnf update - doesn’t help.

Failed to parse PKI file /var/cache/PackageKit/42/metadata/akvis-42-x86_64/akvis.gpg

What does the content of that akvis.gpg file actually look like?

If you run file against it, I’d expect it to report itself as a PGP public key block and viewing it in bat or cat should show you that it’s a standard PGP block… something beginning with:

-----BEGIN PGP PUBLIC KEY BLOCK-----
