I tried three times to install openSUSE-Tumbleweed-DVD-x86_64-Snapshot20170612-Media.iso
to a dell laptop and failed always where a script converts font files. I
believe the failure code was 157. Sorry was frustrated, in a hurry and
didn't note the exact code. The same failure was presented with every
font file being installed.
I was installing from a usb stick which I prepared using imagewriter twice
as I wasn't sure the first succeeded after the failed install above. I
then tried using dd, with same result.
so I installed openSUSE-Leap-42.2-DVD-x86_64.iso using dd to the same usb
stick and prceeded to successfully install to the laptop, and then dup'ed
