+++ This bug was initially created as a clone of Bug #1044741 +++

I did installation from openSUSE-Leap-42.3-DVD-x86_64-Build0279-Media.iso image
and during installation there was internet connection and computer was ONLINE. 
But I found that it tried to use only DVD as repository...

Though default online repositories (oss, non-oss, oss-updates, non-oss-updates)
will be added only if I intentionally pressed to configure online repositories
at dialog for computer role.

If I remember good, in previous versions these four _default_ repos where
enabled by default, and we had option to include _additional_ repositories.
