Upgrade - How to fix 404 errors when updating OP5 Monitor using yum (changes in ITRS OP5 Monitor repositories)?

In September 2019, changes were made to the ITRS OP5 monitor repositories. As a result, we no longer provide the CentOS base and updates repositories. We have also removed old and obsolete repositories.

Customers who have systematically updated Monitor over a long period of time may run in to “404 errors” because yum or dnf can no longer find configured repositories. You may see errors like:

http://repos.op5.com/el6/x86_64/centos/6/base/repodata/repomd.xml: [Errno 14] PYCURL ERROR 22 - “The requested URL returned error: 404 Not Found”

The following needs to be done to ensure your repositories are up to date:

1. Move all of these obsolete OP5 repository files out of the “/etc/yum.repos.d/” directory:

   • op5-system-release.repo
   • op5-system-release-source.repo
   • op5-system-release-debuginfo.repo
   • op5-release-public_beta.repo
   • op5-release-public_beta-source.repo
   • op5-release-public_beta-debuginfo.repo

2. Ensure enabled=1 is set in the base and updates repos in the /etc/yum.repos.d/CentOS-Base.repo repo-file. This will make yum retrieve CentOS updates from official CentOS mirrors.

3. Ensure enabled=1 is set in the op5-monitor-updates and op5-epel repos within the /etc/yum.repos.d/op5-release.repo repo-file.

4. Issue the following command to clear your cache:

   yum clean all
   

Now it should be possible to update your Monitor installation and your CentOS installation using:

yum update
