Rackspace Ubuntu 12.04 server stuck in initramfs after kernel upgrade
- by Znarkus
Can't boot after I did a aptitude full-upgrade and let it update menu.lst (did a diff first and it looked good).
This is what I've done so far in the BusyBox shell:
mkdir /tmp/xvda1
mount /dev/xvda1 /tmp/xvda1
chroot /dev/xvda1
nano /boot/grub/menu.lst
This file looks like this:
title Ubuntu 12.04.1 LTS, kernel 3.2.0-31-virtual
root(hd0,0)
kernel /boot/vmlinuz-3.2.0-31-virtual root=UUID=/dev/xvda1 ro quiet splash

From what I remember, the upgrade added the UUID= string. Should I remove these? Or rather, how do I get my system back online again? Thanks.
Update: Seems like I can't even edit the file.
