CentOS 8 migration fails after EOL with error: Cannot prepare internal mirrorlist: No URLs in mirrorlist #128

Open dskfh opened 2 years ago

dskfh commented 2 years ago

Now that CentOS 8 is history, using centos2ol.sh does not work any more because the CentOS repositories have become unavailable.

Running the script produces something like this:

Right now, I am updating files in /etc/yum.repos.d/, replacing mirrorlist=... with this:

baseurl=http://vault.centos.org/$contentdir/$releasever/[Appstream|...]/$basearch/os/

What is the recommended migration path now, and will centos2ol.sh be updated to handle this automatically?

There is a note about this in the README When I ran into this issue, I updated as you did for all repos, extrapolated from shaneholloman's currently last comment in #126 :

BTW, since centos8 repos have move to vault I also

Change to following line to each respective file:

[root@etp-monitor1 ansible]# vi /etc/yum.repos.d/CentOS-Linux-BaseOS.repo
[root@etp-monitor1 ansible]# vi /etc/yum.repos.d/CentOS-Linux-AppStream.repo

CentOS-Linux-BaseOS.repo baseurl=http://vault.centos.org/$contentdir/$releasever/BaseOS/$basearch/os/ CentOS-Linux-AppStream.repo baseurl=http://vault.centos.org/$contentdir/$releasever/AppStream/$basearch/os/

Comment the mirrors

Agree it would be nice if someone could update the scripts to handle this automatically.
