Then please do that in a different bug report against the installer, with those
logs.

As YaST uses Qt5, it may be related, or not.
So you may want to provide a link to this bug report too.
At least you should definitely specify that you are trying to install on an old
AMD CPU without SSE2 support.

According to the error message, it might as well be ruby that doesn't support
SSE1-only either meanwhile.
Or it might be a completely different problem...

But in any way, the KDE team is not responsible for such installation problems
in the first place.

Thanks.
