Re: BUG #19117: postgresql15-contrib-15.15 for RHEL 9 has conflicting OpenSSL dependencies (3.0.0 and 3.4.0)

Hi,

Just an FYI: OpenSSL 3.5 is a part of RHEL 9.7 (and 10.1) update, so RHEL users are not affected unless they are sticking to a minor RHEL  version -- and I covered them with our sysupdates repo. Alma released 9.7 today with OpenSSL 3.5.

FWIW I have a plan to prevent such issues from happpening in the future. It is under peer review now.


Regards, Devrim
