Hello there,

We've been using packer to create our own custom images and later on deploy those images for bare metal machines with MaaS.I've been struggling to get over the "Error setting up base repository" error doesn't matter what mirrorlist, repo-url I use. I've literally tried everything that I could find from people's responses.

We were using the boot image just fine, I did try using the netinstall and the complete 7Gb iso image - same result all the time.

The original bug is supposed to be fixed in the previous version of 8.2, but I'm using the latest one and it's not fixed. This is the bug - https://bugs.centos.org/view.php?id=16456

In my kickstart file I'm using the closest mirror that we have, which is technically not a mirrorlist, but that's how people managed to resolve it.

url --mirrorlist="http://mirrors.uni-ruse.bg/centos/8.2.2004/BaseOS/x86_64/os/"
repo --name "AppStream" --mirrorlist="http://mirrorlist.centos.org/?release=8&arch=x86_64&repo=AppStream" 
repo --name "Extras" --mirrorlist="http://mirrorlist.centos.org/?release=8&arch=x86_64&repo=Extras" 
repo --name "cloud-init" --baseurl="http://copr-be.cloud.fedoraproject.org/results/@cloud-init/el-stable/epel-8-x86_64" 
repo --name "epel" --mirrorlist="https://mirrors.fedoraproject.org/metalink?repo=epel-8&arch=$basearch&infra=$infra&content=$contentdir"

As a mirrorlist i tried all variations from the bug thread in CentOS, nothing worked.

I'm open for any suggestions.
