APT repository snapshot doesn't contains Translation-en

Hello there,
we have just started to test Nexus Repository OSS out and are encountering an issue with the snapshot functionality for a Debian repository.

# apt -o "Acquire::https::Verify-Peer=false" update

Seems like there was a bug in apt-mirror, which already is fixed: https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=932379

InRelease also points to Translation-en.xz, which some kind of proofs this type of bug

Does this piece of software use apt-mirror, or is there something else I can check?

Thanks!

Did some further research. It seems like whole i18n and source folders aren’t included in snapshots repository, so the needed meta files can’t be loaded by apt.
The reason might be the exclusion of these folders in https://github.com/sonatype/nexus-public/blob/9f495755f08bfc64cc58415432bf95a6cf4aab92/plugins/nexus-repository-apt/src/main/java/org/sonatype/nexus/repository/apt/internal/AptFacetHelper.java#L48

I will create an issue on GitHub and ask for further help there.

Best regards,
David
