It looks like that your /etc/default/grub file has been modified. Perhaps because you've manually edited it in order to apply those "power saving tweaks".

Try restoring the file:

sudo install -m644 /usr/share/grub/default/grub /etc/default/grub

Followed by continuing the installation:

sudo apt-get install

(if that fails, sudo apt-get install -f)

I have the same error on Precise x386 I can't uninstall this package. All I want is to get rid of it because it doesn't allow me to install or update anything. It has some wierd dependancies. I tried to
"sudo update-initramfs -u"
and choose xubuntu logo theme but no success. I had uninstalled KDE but this single file remained. Now I use Xfce. I now it is probably my fault but I hope it can be fixed somehow. I can't even install kubuntu-desktop now.

[axel (axel334)]

I could't fix it nor wait, so I reinstalled my system to the new version. So my notification about thi bug is kind of invalid now. But it appeared and it think it was due to mixing (instaling, uninstalling) different desktop environment.

[João Matos (matosmeister)]

I disabled the plymouth theme and uninstalled the packages (there were 4 causing errors) and now it's all back to normal.

Thank you for taking the time to report this bug and helping to make Ubuntu better. Reviewing your log files attached to this bug report it seems that there is a problem in the configuration of your '/etc/default/grub' file. Keep in mind than any kernel parameters should have double quotes around them like so: GRUB_CMDLINE_LINUX_DEFAULT="quiet splash". Please review your changes to '/etc/default/grub' and try running 'sudo update-grub' again. In the event they you are able to resolve your issue please set this bug's status to Invalid. If you are not able to resolve the issue please attach the file '/etc/default/grub' to the bug report. Thanks and good luck!
