I just got a Dell XPS 13 with Ubuntu 14.04 pre-installed and when I tried to run software updater it went gray and stalled at "Configuring grub-efi-amd64"
I forced shutdown and when I rebooted the OS couldn't boot. It ended up using Dell's recovery thing, rebuilt Ubuntu and started over as a fresh install.
I've installed Ubuntu myself before on previous laptops and never had this problem. I've added some pictures below to help illustrate what happened. Sorry about the glare, I didn't realise it was that bad at the time.
I'd love to solve this problem if anyone has any ideas.
Kernel panics normally happen when updates are taking place and they are interrupted.
I deal with this alot and its normally not the end of the world but it can be if you do not have a secondary kernel as a backup on the machine.
When booting up the laptop look for a screen that lists several different kernels. The top one is the most up to date and in this case the corrupt kernel.
Hit the down arrow at this screen. (The list will go away fast if you do no push anything) Hitting the down arrow a few times untill you see the menu pop up is a easy way not to miss it.
Then just highlight the secondary kernel. If you system boots then we can clean out the corrupted packages then rerun updates.
I would also recommend running updates via terminal. Its is very easy and I trust it way more than any software center application.
I usually do update via the terminal as well as the updater. Although the terminal update seems to be having trouble too. Looks like it can't download the files it finds???:
I also can't seem to get my grub menu at boot. I'm holding down shift at startup; that's right isn't it?
I've never had this much trouble with Linux before. I thought since it was coming pre-installed and optimised for the machine that things would go smoothly. Guess I was wrong haha!
