After running
sudo apt-get dist-upgrade today, it installed
linux-image 3.13.0-68.

This seems to have broken something because the server will not boot.

However if I select a previous version such as
3.13.0-67 then the server boots fine.

How can I make it start with
3.13.0-67 by default?

And would I still have the option to upgrade the next time there is a kernel update?

Based on what I read one can edit
/etc/default/grub apparently, but I am not wrapping my head around it.

Here are the contents of that file in case it helps:


# If you change this file, run 'update-grub' afterwards to update
# /boot/grub/grub.cfg.
# For full documentation of the options in this file, see:
# info -f grub -n 'Simple configuration'

GRUB_CMDLINE_LINUX_DEFAULT="splash nomodeset"
GRUB_CMDLINE_LINUX=""

What's odd to me is that I got an update for 3.13.0-70 today..?
Perhaps re-run an update to see if you get that too.
