Hello. I am aware of this thread
but it is marked as solved.
The iso file I downloaded has the correct md5sum (c98650e0ee446d0570c104dd6e8c5b41).
I have tried several burns using GnomeBaker, kde-services and k3b respectively. In each case the disk returned the same md5sum (635dfb7d48dae1be46cf610a3f501654) which differed from the iso md5sum. I created an iso from one of the burns and the new iso had the same md5sum as the disk.
I tried installing to the hard drive this morning. While I was selecting the partitions to be used, the installer crashed.
At this point, the exercise looks like a lost cause.
Can anyone suggest a way to proceed?
