[Spacewalk-list] issue after dnf update or yum update in rhel8

Mon Mar 23 15:18:20 UTC 2020

Hi

Same. Had a lot of issues with variations of the "cannot install the best update candidate" Issue when using Spacewalk managed repos for Centos 8 clients.

I believe it is caused by the modules issue much discussed. I was able to get it working on one machine after 8.1 released, but not on others - and then the original one reverted to failing on another package after a few days.

Only reliable workaround for C8.1 clients I have is to remove it from all Spacewalk Channels and trigger a remote command for groups using spacecmd of "yum -y update"

This works but obviously doesn't give as much transparency as proper spwk management.

Hi,

I have this issue, too, but was not able to solve it yet. I hope an update to Spacewalk 2.10 would fix it.

Freundliche Grüße / Kind regards

I think it's dnf not a Spacewalk issue. Does it work if you register the
machine directly without Spacewalk server?
