Обсуждение: sysupdates yum repos are gone

Hi Devrim and the PGDG RPM team,

First of all, thank you for your continued efforts in maintaining the PostgreSQL YUM repository.

I'm writing to inquire about the status of the sysupdates yum repositories. We've noticed that these repositories are now returning 404 errors, and I wanted to understand whether this is an intentional change or a temporary issue.

Observed behavior:

1. The following repository URLs are returning 404:

   • https://download.postgresql.org/pub/repos/yum/common/pgdg-centos8-sysupdates/redhat/rhel-8-x86_64/repodata/repomd.xml

   • https://download.postgresql.org/pub/repos/yum/common/pgdg-rocky9-sysupdates/redhat/rhel-9-x86_64/repodata/repomd.xml

2. The howto page at https://yum.postgresql.org/howto/ still references the sysupdates repository, stating it "distributes LLVM and CLANG packages for Rocky Linux / AlmaLinux for the times when RHEL releases a minor update and clones need to take some time to catch up."

3. The repository definitions still exist in /etc/yum.repos.d/pgdg-redhat-all.repo (from pgdg-redhat-repo-42.0-63), causing dnf update to report errors when these repos are enabled.

4. Search engine caches suggest the pgdg-centos8-sysupdates directory existed as recently as May 2025, containing packages like clang-19.1.7.

Questions:

1. Have the sysupdates repositories been intentionally removed or deprecated?

2. If so, is there an alternative approach now recommended for Rocky/AlmaLinux users who need updated LLVM/Clang packages during the RHEL minor version lag period?

3. Should users simply disable these repository definitions in their configurations going forward?

Thank you for your time and for all the work you do for the PostgreSQL community and happy holidays

Best regards, Ruohang Feng, Vonng

This is an intentional change. Removed them in full (see below)

Sorry about that, forgot to remove mention to sysupdates repo from
there. Fixed.

Are you sure? I removed them along with -62. Can you please check if you
have an pgdg-redhat-all.repo.rpmnew file under /etc/yum.repos.d or not?

Yes. See this news item for details:

https://yum.postgresql.org/news/postgresql-rpms-multiple-rhel-minor-versions/

We now support multiple RHEL minor versions, so this is not a problem
anymore.

Again, latest repo RPMs do not have those.

You are welcome. Happy holidays!
