Bug description:
As part of Ubuntu key rotation strategy, we rely on dual-signing
(inline, or detached) such that validation with at least one key
available in a keyring should be trusted, without using web-of-trust.
However, it seems to be only correctly so far implemented by the apt's
gpgv method.
Ideally, we should ship an easy enough to use the helper that is `like
gpgv` to use, and possibly reusing apt's gpgv code and/or exposing it
via apt-key's verify.
The problem seems to be that 1 good sig + 1 no public key available,
results in gpgv exiting with 2, instead of 0 or 1.
Ideally it should be easy enough to use gpgv/gpg to verify that at
least one signature is good, and decrypt/extract signed contents only.
More details and reproducers to follow.
