This issue is purely informational, you do not need to take any action. Thank you for your work maintaining proj in EPEL 9. Red Hat considers this package important enough to promote it to official RHEL. It will be part of RHEL 9.7. Please do not update proj in EPEL 9 so the RHEL version can have a higher version and release. When RHEL 9.7 is released, EPEL automation will remove proj from EPEL 9 and close this bug.

Just from information:

One problem here:
The situation right now is that proj from EPEL-9 conflicts with RHEL-9 appstream. This prevents several packages from being updated:

[root@mycroft~]$ LANG=C dnf update

(try to add '--allowerasing' to command line to replace conflicting packages or '--skip-broken' to skip uninstallable packages or '--nobest' to use not only best candidate packages)

If you try to "force" the update to the @appstream version, quite a few dependent packages from EPEL are affected:

These dependencies should be resolved together with dropping proj from EPEL.

I just checked, and proj is not in RHEL 9.6, so this is not affecting RHEL users yet.
It is in CentOS Stream 9, and yes, that currently is a problem.

When RHEL 9.7 is released we will be removing proj from epel9.
At that point, affected epel packages will need to be rebuilt.

Hi, 

epel-proj package needs to go.

Working on it.
proj was released in RHEL 9.7
It seems tagging permissions changed since our last RHEL release and we can't untag our usual way.

proj is now in RHEL9 as of RHEL 9.7.
It has been retired from EPEL9.
It will take a day or two before it is out of the epel9 repositories and mirrors.
