Hello together,

I hope, this is the right spot. In my deployment, I catch an error
constructing metadata for dnf.

msg: 'Failed to download metadata for repo ''pgdg16'': repomd.xml GPG
signature verification error: gpgme_op_verify() error: No data'

I went to the url, where it should download this metadata and I find an
empty repo.xml.asc.
(https://download.postgresql.org/pub/repos/yum/16/redhat/rhel-9-x86_64/repodata/)

Going to the respective repos for version 15 and 17, there is a repo.xml.asc
file containing a PGP signature.

This seems unintended. A change to repo.xml.asc in version 16 was made on
03-Aug-2025 15:33.

I would be happy for remediation,

Thanks,

Thomas
