It doesn't matter whether or not this is caused by having done anything manually with grub before. If you have a system that works 100% fine, you run dist-upgrade and you get a broken system that won't even boot, there's a bug, be it in grub or in dist-upgrade. At the very least, dist-upgrade MUST check if there's something that will prevent the upgrade to work, refuse to perform the upgrade (or warn you) and tell you exactly what needs to be fixed before upgrading.
In my case, I never touched anything grub-related manually, or if I did, it was to fix something that the previous upgrade or clean install screwed up because of a bug. -- 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
