Merge 48ad749965 into c407e2ff84

Starting with Debian Trixie, `apt secure` relies on `sqv` to do its verification, which doesn't support the GPG keybox database format.

At the same time, using the standard PGP base64 format makes the verification fail for versions of `apt secure` which relies on `gpg`, as the subkey isn't detected there.

Fixes #1055
