Hello. I've checked the recent archives and cannot find mention of this issue,
and tried the irc channel last night where another user confirmed they had also
encountered this. If it has been discussed already, please direct me
accordingly.
Since the Centos repos were updated to symlink /8 to the new /8.1, Spacewalk
managed updates are failing consistently on all our Centos 8.x machines.
My research suggests that this is because Spacewalk is not handling modules
when populating its repos. This causes downstream updates to fail.
My questions are:
1) Am I right in my conclusions?
2) If so, will Spacewalk be updated to correctly handle Centos 8.1+ modules?
Thanks
Background:
* Spacewalk 2.9 running on Centos 7 and managing 139 Centos machines; 6.10,
7 and a dozen or so 8.x Each client runs the spacewalk-2.9-client suite.
* All our systems (including Centos 8.0) were behaving as expected.
* I have not knowingly installed a module, but it seems their use is
largely transparent now.
Problem:
When running a package update through Spacewalk, or running dnf update from the
client locally, the dnf/yum process fails. (Full logs below)

(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)
Using -allowerasing ends up removing perl and breaking quite a few things.
