This was an installation on NVMeoF with a hand-crafted autoinst.xml file that defines a minimal installation. The same autoinst.xml works fine on SLE15-SP4.

autoinst.xml file
Comment 2 Stefan Hundhammer 2023-02-21 10:17:13 UTC 
Code location:

https://github.com/yast/yast-bootloader/blob/master/src/lib/bootloader/finish_client.rb#L57

so ::Bootloader::BootloaderFactory.current is nil.
Comment 3 Stefan Hundhammer 2023-02-21 10:18:31 UTC 
The bootloader section from autoinst.xml:

> <bootloader t="map">
>   <global t="map">
>     <append>preempt=full mitigations=auto security=apparmor console=ttyS0,115200 console=tty0</append>
>     <cpu_mitigations>auto</cpu_mitigations>
>     <gfxmode>auto</gfxmode>
>     <hiddenmenu>false</hiddenmenu>
>     <os_prober>false</os_prober>
>     <secure_boot>true</secure_boot>
>     <terminal>gfxterm</terminal>
>     <timeout t="integer">8</timeout>
>     <update_nvram>true</update_nvram>

Comment 4 Stefan Hundhammer 2023-02-21 10:21:13 UTC 
Martin, FYI: I found out recently that Bugzilla can be tricked into not mangling preformatted text into garbage when you simply prefix each line with "> " to mark it as a quote. See my previous comment.

  Saving /etc/sysconfig/bootloader for grub2-efi


But I don't see a grub2-install call anywhere. Should that have come after bootloader_finish?
Comment 7 Stefan Hundhammer 2023-02-21 10:58:01 UTC 
Josef, please have a look.
Comment 8 Josef Reidinger 2023-02-21 11:06:02 UTC 
It is caused by change in yast2-network. I see that in logs is yast2-network-4.5.15 and fixed version is 4.5.16.

See changelog entry https://github.com/yast/yast-network/blob/master/package/yast2-network.changes#L4

So already fixed and just waiting to be in the latest leap.
