Subject: PGDG16 repository error - repomd.xml.asc is empty
Date: Mon, 4 Aug 2025 17:01:00 +0200
Message-ID: <CAODqTUYYjv_JeqRergOburRKtRQXSL_V-eD0vLH1FwnzXsnuSA@mail.gmail.com> (raw)

Hello,
I've found that PGDG16 repository access is failing (while last Thursday it
worked):

Example - pgdg 17 works, pgdg16 doesn't work:

$ yum repolist pgdg16 pgdg17
repo id          repo name
                                        status
pgdg16         PostgreSQL 16 for RHEL / Rocky / AlmaLinux 9 - x86_64
        enabled
pgdg17         PostgreSQL 17 for RHEL / Rocky / AlmaLinux 9 - x86_64
        enabled

$ yum -y --disablerepo=* --enablerepo=pgdg17 info postgresql17

management system (DBMS).
             : The base postgresql package contains the client programs
that you'll need to
             : access a PostgreSQL DBMS server. These client programs can
be located on the
             : same machine as the PostgreSQL server, or on a remote
machine that accesses a
             : PostgreSQL server over a network connection. The PostgreSQL
server can be found
             : in the postgresql17-server sub-package.
             :
             : If you want to manipulate a PostgreSQL database on a local
or remote PostgreSQL
             : server, you need this package. You also need to install this
package
             : if you're installing the postgresql17-server package.

Error: Failed to download metadata for repo 'pgdg16': repomd.xml GPG

The PGP signature for PGDG16 repo is empty:

The only workaround I've found is to set repo_gpgcheck = 0
in /etc/yum.repos.d/pgdg-redhat-all.repo for pgdg16.

Thanks for fixing or providing advice on how to securely handle this issue.

Kind regards Ales Zeleny
