as the admin-users might have got to know. RedHat canceled long term support for CentOS8, and wants to go with CentOS8stream.
so the repo for CentOS8Stream is https://ftp.halifax.rwth-aachen.de/centos/8-stream/BaseOS/x86_64/os/
(https should work, double check for typos)
Phase1 setup of CentOS8Stream as VirtualBox 6.1 guest
Phase2 setup of CentOS8Stream basic installation
including going through all software selection menu possibilities
- it is possibly to select minimal installation in software selection (and thus run a headless server, default is server with gnome3 gui)
- security policy selection screen is now not a menu but wants a url specified
it seems the CentOS 7 NetInstall.iso images of CentOS do not come with any packages…
so you will have to provide a mirror, University https://rwth-aachen.de does a magnificent job with that, even properly configured https (!)
so what you do is
- Networking is disabled per default, go to Network and put it to “on”
- go to software and type: https://ftp.halifax.rwth-aachen.de/centos/7/os/x86_64/
- find the exact directory for the version one tries to install here: https://ftp.halifax.rwth-aachen.de/centos/
- for CentOS 8 that should be: https://ftp.halifax.rwth-aachen.de/centos/8/BaseOS/x86_64/os/
- older versions that receive no updates anymore: http://vault.centos.org/
- that looks like for CentOS8: https://ftp.halifax.rwth-aachen.de/centos/8/BaseOS/x86_64/os/

“EPEL (Extra Packages for Enterprise Linux) is a volunteer-based community effort from the Fedora project to create a repository of high-quality add-on packages that complement the Fedora-based Red Hat Enterprise Linux (RHEL) and its compatible spinoffs, such as CentOS.
As part of the Fedora packaging community, EPEL packages are 100% free/libre open source software (FLOSS).” (src)
yum -y install epel-release; yum -y update; yum repolist
Content in the BaseOS repository is intended to provide the core set of the underlying OS functionality that provides the foundation for all installations. This content is available in the RPM format and is subject to support terms similar to those in previous releases of CentOS.
Content in the AppStream repository includes additional user space applications, runtime languages, and databases in support of the varied workloads and use cases.
Content in AppStream is available in one of two formats:
- the familiar RPM format and
- an extension to the RPM format called modules.
Both BaseOS and AppStream content sets are required for a basic installation. For installation instructions, see the Performing a standard installation Performing an advanced installation documents.
