Well, gosh. That was EASY! Here's the simple steps I used to fix this; the sort of thing any generic user should be able to pull out of thin air. The gist is I booted to an xubuntu 14.04 live CD, mounted and chrooted to my normal system, then ran dpkg-reconfigure and update-grub. I selected both /dev/sda and /dev/sda1 (I think all I needed was /dev/sda) on the reconfiguration.
I expect SOMEONE will gripe about running on a root prompt, but that's been my modus operandi for doing rootish things since K&R invented the darn thing back when I was a yout. root@xubuntu:~# cryptsetup luksOpen /dev/sda5 crypt Enter passphrase for /dev/sda5: root@xubuntu:~# cd /media/xubuntu/fb9186c7-9f3d-4a88-8d4b-9c8849e05a38/ root@xubuntu:/media/xubuntu/fb9186c7-9f3d-4a88-8d4b-9c8849e05a38# mount /dev/sda1 boot root@xubuntu:/media/xubuntu/fb9186c7-9f3d-4a88-8d4b-9c8849e05a38# mount --bind /proc proc root@xubuntu:/media/xubuntu/fb9186c7-9f3d-4a88-8d4b-9c8849e05a38# mount --bind /dev dev root@xubuntu:/media/xubuntu/fb9186c7-9f3d-4a88-8d4b-9c8849e05a38# mount --bind /sys sys root@xubuntu:/media/xubuntu/fb9186c7-9f3d-4a88-8d4b-9c8849e05a38# chroot ./ root@xubuntu:/# dpkg-reconfigure grub-pc root@xubuntu:/# update-grub -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1289977 Title: Ubuntu 14.04 Update breaks grub, resulting in "error: symbol 'grub_term_highlight_color' not found" To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/grub2/+bug/1289977/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
