Problem lies in conflict with grub and kernel 3.8.0-35. Here is a workaround:
# apt-get purge dose not succeed but synaptic "completely remove" option does sudo apt-get install synaptic from synaptic, completely remove grub, grub2, grub-pc, grub-bin, grub-common, etc. # you can search for 'grub' then sort on 'status' to find what is installed then 'com[letely remove' them. close synaptic and from the terminal type sudo apt-get install grub2 sudo update-grub # Before anything else, update the kernel sudo apt-get update && sudo apt-get upgrade now you should be able to install anything you like, including gkvim, without getting an error message telling you that /etc/default/grub is not found or is invalid. You can alsoun-install grub and re-install any other bootloader which you may have been using such as burg as was the case with me. This is just a hack around the issue. The issue still exists. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1265428 Title: package grub-pc 1.99-21ubuntu3.14 failed to install/upgrade: subprocess installed post-installation script returned error exit status 127 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/grub2/+bug/1265428/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
