Classic Installation DVD Mageia 8 ends in missing packages

I have burnt the Mageia-8-x86_64.iso on a DVD. Then I tried a fresh installation with formatting of the / partition. Plasma Desktop
However the installation reports failures of missing packages. I have also added a network http or ftp connection with the intention that the missing packages could be loaded from there. And the error reports remain. The installation is aborted.
