I've just tried to upgrade my OpenSuSE Leap 15.0 based home server to 15.2 by using a self-made DVD containing the official image. It failed. First, the installer announced an I/O error whilst trying to install some package (I don't know which, unfortunately), and stopped. When rebooting the system and trying to upgrade for the second time, the installer already stopped at step #3 (repo selection) with the following error message (translated):
Base installation product not found. Installation stopped.
I gave the upgrade a third chance, but received the abovementioned error message. The 15.0 system seemed untouched, but the firewall had to be reinstalled.
Here is my system config:
╭─root@valen ~ ╰─➤ sysinfo -v (by hxtools sysinfo) [valen] openSUSE Leap 15.0 | Linux 4.12.14-lp150.12.82-default x86_64 | 8-thr Intel(R) Xeon(R) CPU E3-1231 v3 3800MHz | Load: 0.42 Tasks: 187 | Mem: 234/7931MB | Disk: 809/916GB | Gfx: ASPEED Technology, Inc. ASPEED Graphics Family @ 1920x1080
The DVD was fairly fresh (2 days old), and the burning app (K3b) checked the disc and found no errors.
What's the problem here? Is the DVD maybe faulty despited being declared flawless by K3b?
