Description Stéphane Couturier 2017-02-14 08:43:43 CET 
The "drakboot" program crashed. Drakbug-17.71 caught it.


I realized that although I have done all updates of cauldron, I am running on an old kernel.
uname -a  is giving:
Linux localhost 4.6.3-desktop-1.mga6 #1 SMP Sat Jun 25 11:20:38 UTC 2016 x86_64 x86_64 x86_64 GNU/Linux

So I meant to reinstall the boot loader, hoping it would fix the issue and use the kernel-desktop-latest by default, and I was just starting the configuration of boot from MCC when it crashed.

Hi Stéphane,

This is a duplicate of bug 16840, even if there it happened during a Live install. In another duplicate bug, 18461, Thierry asked:

It would be nice if you could attach that file to bug 16840

After that, I recommend running an "upgrade install" with a network iso or even 6sta1. That often fixes the kind of problems you see.
