After some updates of Opensuse’s Leap 15.6 systems via a variety of repositories (including the SLES 15.6 repo as the main and leading repository), one of my installed packages was removed. I am talking about a very central one, namely “kernel-default-devel version 6.4.0-160600.21.3-x86_64”. (It can be found in the main repository of the 15.6 distribution.) This was in so far reasonable as I have no longer any respective kernel installed. All used kernels are of version “6.4.0-156000.23.xxx”.

However, the removal of the old kernel-default-devel package caused difficulties with the Nvidia drivers in Opensuse’s respective repositories. The installation and compilation of the required diver module delivered by package “nvidia-driver-G06-kmp-default” would fail. It requires the original kernel-default-devel version 6.4.0-150600.21. As a consequence on the affected systems the Nvidia driver could no longer be loaded.

A supplemental installation of the original kernel-default-devel package (coming with the distribution) remedied the problems. Hope this helps others who experience similar problems during system updates.
