I reported this on Mageia; you may find the following helpful. https://bugs.mageia.org/show_bug.cgi?id=12423
As to what is happening, it has got *nothing* to do with the terminal_highlight_color. Grub has 2 parts: The early stage, installed in the drive's bootsector The rest of the modules, installed in /boot/grub These two are getting out of sync, and the ABI symbol mismatch is because there is an older version of one than of the other. I suspect that: 1. The grub package, which installs binaries into /boot/grub is being updated 2. Something is failing to correspondingly update /dev/sdX's boot sector 3. No warning is emitted. ** Bug watch added: bugs.mageia.org/ #12423 https://bugs.mageia.org/show_bug.cgi?id=12423 -- 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-release-upgrader/+bug/1289977/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
