There is unfortunately no xorg-x11-server-Xorg-1.20.11-2.el8 in Fedora's koji yet. I just tried a scratch build and that picked up the .10. It is also not possible to do build overrides with EPEL builds if packages belong to core of RHEL/CentOS. We'll have to wait until this hits koji and they rebuild.

Sounds like a major problem with EPEL and CentOS 8 stream then. This is quite a significant source of problems for packages compatibility

Sounds like a problem that's already been solved. :)

xorgxrdp needs to be branched and rebuilt on epel8-next.
bojan if you need help with that please let me know.  But the instructions are basically

fedpkg request-branch epel8-next
# wait for the branch to be created
fedpkg switch-branch epel8-next
git merge epel8
fedpkg push
# (optional) bump your release, make edits or whatever you want
fedpkg build
fedpkg update
# follow the usual update steps

Yeah, I can try that.

Hello Bojan,

I asked on the EPEL mailing list and Troy was kind enough to answer. I didn't know about epel-next. Would you consider building xorgxrdp for epel-next please?

Thank you.
Kind regards.

Thank you so much! I'll give it a try when ready.

Yes, tomorrow, my time.

I'm concerned about why xorgxrdp has this strict version requirement.

    [root@rhel8-container:~]# repoquery --quiet --requires xorgxrdp | grep server
    xorg-x11-server-Xorg(x86-64) = 1.20.10

This was implemented here [0], without an explanation as to why it's needed.  This means that any time xorg-x11-server-Xorg gets a new version, xorgxrdp has to be rebuilt.  That is the case here, where rhel8 has 1.20.10, but c8s has updated to 1.20.11.  A rebuild in epel8-next will solve this, but wouldn't it make more sense to relax the requirement instead?  xorg-x11-server-Xorg provides several abi virtual provides, defined in the pkgconfig file, that seem like a better fit for this.

    [root@c8s-container:~]# grep abi /usr/lib64/pkgconfig/xorg-server.pc
    abi_ansic=0.4
    abi_videodrv=24.1
    abi_xinput=24.1
    abi_extension=10.0

    [root@c8s-container:~]# for abi in ansic extension videodrv xinput; do pkgconf --variable abi_$abi xorg-server; done
    0.4
    10.0
    24.1
    24.1

Those abis match across 1.20.10 and 1.20.11.

    [root@rhel8-container:~]# repoquery --quiet --provides xorg-x11-server-Xorg-1.20.10-1.el8 | grep abi
    xserver-abi(ansic-0) = 4
    xserver-abi(extension-10) = 0
    xserver-abi(videodrv-24) = 1
    xserver-abi(xinput-24) = 1

    [root@c8s-container:~]# repoquery --quiet --provides xorg-x11-server-Xorg-1.20.11-2.el8 | grep abi 
    xserver-abi(ansic-0) = 4
    xserver-abi(extension-10) = 0
    xserver-abi(videodrv-24) = 1
    xserver-abi(xinput-24) = 1

If xorgxrdp can be adjusted to require these virtual provides instead of the exact xorg-x11-server-Xorg version, the epel8 package would be compatible with both rhel8 and c8s without needing to rebuild it in epel8-next.  epel8-next would still be an option if c8s ever rebased to a newer version that changes the abi.

Xorg binary enforces this at runtime, so we just follow that in packaging to avoid disappointment.

After some investigation, I can see that other xorg modules don't do this.  xorg-x11-server-devel has a script named xserver-sdk-abi-requires that most other xorg module packages use generate the abi requires.  Here is an example from xorg-x11-drv-fbdev [0].

    Requires: Xorg %(xserver-sdk-abi-requires ansic)

Of the abis listed in the pc file, only ABI_CLASS_VIDEODRV and ABI_CLASS_XINPUT are listed in the xorgxrdp code base, so I think you'll just need lines for those.  I've sent a pull request to implement this on rawhide, which can be cherry-picked back to the epel8 branch.

OK, we can try that. Ideally, this package should be rebuilt when underlying dependencies change, automatically. There is an old bug along those lines.

I gave a quick try to the package in epel-next-testing and the deps are now resolved! The package / system can be installed and upgraded without problems now.

Thank you very much to everybody.
