Troubleshooting Linux Patching Issues

My Staging Server Setup DP fails at "Channels Information Collection" step with the error message "Could not fetch the subscribed channels properly". How do I fix this?

This error is seen if there is any network communication error between up2date and ULN. Check if up2date is configured with correct proxy setting by following https://linux.oracle.com/uln_faq.html - 9. You can verify if the issue is resolved or not by using the command, up2date –nox –show-channels. If the command lists all the subscribed channels, the issue is resolved.

My "up2date –nox –show-channels" command does not list the subscribed channels properly. How do I fix this?

Go to /etc/sysconfig/rhn/sources files, uncomment up2date default and comment out all the local RPM Repositories configured.

How can I register to channels of other architectures and releases?

Package Information Job fails with "ERROR: No Package repository was found" or "Unknown Host" error. How do I fix it?

Package Repository you have selected is not good. Check if metadata files are created by running yum-arch and createrepo commands. The connectivity of the RPM Repository from OMS might be a cause as well.

Compliance Collection is a job that runs once in every 24 hour. You should wait for the next cycle of the job for the Compliance report to update itself. Alternately, you can go to the Jobs tab and edit the job to change its schedule.
