I was wondering what was up with this. Had no idea they stopped updates for CentOS 8. I am pretty late to this news it seems.

They didn’t really give a reason why, not from what I can see. I guess they just wanted to end the project? Maybe someone else will pick it back up in the future. Good to know it will be archived but I likely won’t return to it after this since it is very likely to become increasingly unstable and unsafe to use as time goes on.

Thanks for the list and recommendations of alternatives! Just saved me time looking around.

Thank you very much. I am new to Linux and this issue was driving me crazy reading all the posts related to why my dhclient / DHCP wasn’t working or file was not found etc…
Hopefully, this new upgrade should be the fix I was searching for.

If you just want to install packages on Centos 8 without upgrading to CentOS 8 Stream, type

# sed -i 's/mirrorlist/#mirrorlist/g' /etc/yum.repos.d/CentOS-Linux-*
# sed -i 's|#baseurl=http://mirror.centos.org|baseurl=http://vault.epel.cloud|g' /etc/yum.repos.d/CentOS-Linux-*

Now you can run something like:
# dnf install --assumeyes epel-release
root@admin-linux]# dnf install --assumeyes epel-release
