Help with prerequisite CentOS 8.5

mrbaseman commented 2 years ago

Hi,

I wanted to migrate CentOS installations of a couple of VMs which were powered off some time. They were still on CentOS 8.4 and an update to 8.5 failed because of the EOL of CentOS. I came across this blog, which helped me to solve the problem:

https://techglimpse.com/failed-metadata-repo-appstream-centos-8/

Maybe it referring to it helps others to solve the same problem more quickly.

Cheers, Martin

migrate2rocky accounts for this by changing the repourls to point to the CentOS Linux 8.5 vault mirror that we maintain. If you're getting an error that is fixed by updating from CentOS vault then that is likely a bug in migrate2rocky. Can you supply the migrate2rocky.log file from the failed migration so that I can review it and see if there's something I can do to fix the issue?

The problem was not during running migrate2rocky.

I have assumed that I shall update the Centos installation to 8.5 before running the migration script. The first item in the documentation "CentOS Stream, CentOS, Alma Linux, RHEL, or Oracle Linux running well on a hardware server or VPS. The current supported version for each of these is 8.5." has made me believe this.

Actually, a bit further down, this documentation instructs the reader to "check out migrate2rocky's README page". I must admit that I haven't checked this README.md carefully enough, because at a second look, I find similar instructions to the ones that I was suggesting in the current issue in the EL 8.0 migration section of the README.md

I'll close this issue. Anyhow, feel free to take away the message that EOL of CentOS has made the migration a bit more complicated, and improving the documentation in this aspect might help users to migrate their systems.

(probably the repository of the rocky-tools is the wrong place to report this)
