The same error message popped up when I tried to install Fedora KDE Plasma on wiped out ssd.
I thought the bootable drive or the file was bad at first. I saw many of them solved the issue recreating the bootable drive or through the source, the file itself. Unfortunately, I learned that it wasn't the case for me after I spent a quiet some time on it.. But I found something thou.
The error message only pops up when it's Pop os, I tried to install. Actually, Fedora KDE made screen go black, silence, nothing happened. I just thought it was the same issue whether it showed the error message or not.
Kubuntu, exactly same thing happened as Fedora KDE. But one of four I tried, had no trouble through, all the way. Only LMDE, out of the ones I tried, wasn't affected whatever the problem is. All of them were under exactly the same condition. what is it. Does anyone know what this is about. What is difference.
Please enlighten me if you see what the issue could be or you have suggestions for me just based on what I said
