CentOS 8 installation: Error setting up base repository

As a follow-up to my previous article about CentOS 8 issues, I’d like to show how to fix a similar issue with a new CentOS 8 installation, namely, “Error setting up base repository”. I was setting up CentOS on a VMWare virtual machine, and here’s how the issue looked like:

The reason is, again, that the base repository was removed on January 31, 2022 due to end-of-life of CentOS 8. Good thing is that the legacy repository is still available, just under a different address: https://vault.centos.org

To fix the issue, first go to “Network & Host Name” section, enable the Ethernet connection and click “Done” (you might need to set up proper network settings in a more complex case):

Now go to “Installation source”. The “On the network” section should now be editable. Tip: if your “Installation source” button is not clickable and greyed out, click on any other section button and go back by pressing “Done”, this should reset the UI.
