I tried doing an upgrade of a machine (Intel NUC DN2820FYKH w/ Latest Bios) that had 13.1 installed. During the configuration, it asked if I wanted to configure the network, but failed.
Steps to Reproduce
Burn x86_64 ISO image onto USB thumb drive.
Insert thumb drive into INTEL NUC.
During power-on, press F10 and boot from the USB thumb drive.
At the SUSE boot menu, select the Upgrade Option.
The partition containing the current install is show. Select next.
A screen appears showing the various repositories that are removed. Hit Next.
A dialog appears saying “Network is not configured. Online sources defined by product require and Internet Connection. Would you like to configure it?”. If you select Yes, it stays stuck - the dialog keeps re-appearing.
If you select no, it displays “Error cannot download list of repositories - No Network Configured”.
Also, at several points through the upgrade process, the system would hang. One of the debug consoles would show the attached image. This set of messages was displayed at least 4 or 5 times.

When doing a clean install, I was able to configure the network successfully.
