I then restarted. But I first switched the video to use “virtio” rather than “QXL”. That’s because of bug 1103426.
I also forgot to mention that I set it to use UEFI rather than BIOS – I already made that change for the first install attempt. Beyond that, I went with defaults.
On my second attempt, I did not run into that digest verification problem. I allowed the install to proceed, with “generic desktop” as the selection. And I seem to have a good install.
I’m not sure what’s the difference between our systems, that you had a panic and I didn’t.
