Ubuntu Server 14.04.2 LTS x86_AMD64 running on a Lenovo Thinkpad T61 with an LVM encrypted hard disk.

I run this script every week or so to upgrade packages:

sudo apt-get update -ymu
sudo apt-get upgrade -ymu
sudo apt-get autoremove -ymu
sudo apt-get autoclean -ymu
sudo apt-get check -ymu
sudo apt-get check --fix-missing -ymu
sudo apt-get update -ymu
sudo apt-get upgrade -ymu
sudo apt-get autoremove -ymu
sudo apt-get autoclean -ymu
sudo apt-get check -ymu
sudo apt-get check --fix-missing -ymu
sudo reboot

Managed to copy this from putty before it closed, but the formatting is a bit screwed up: http://pastebin.com/6jP1XXX3

After the script-initiated reboot, I got a kernel panic.

Did a hard reboot, GRUB popped up, selected 3.13.0-49 regular mode, got kernel panic.

Did a hard reboot, GRUB popped up, selected 3.13.0-49 recovery mode, got kernel panic.

Did a hard reboot, GRUB popped up, selected 3.13.0-48 regular mode, system booted fine.

I'm not sure how to go about fixing this; I think it was caused by this:

The following packages will be REMOVED:
linux-headers-3.13.0-46 linux-headers-3.13.0-46-generic
linux-image-3.13.0-46-generic linux-image-extra-3.13.0-46-generic

Any ideas?

  • 3.13.0-49 panicked for me on my ASUS x64 desktop. I didn't copy down the stacktrace. I'm also using 3.13.0-48 for now. – Adam Monsen Apr 17 '15 at 15:15
