Thanks for your report. There is a syntax error in /etc/default/grub: 11: i915.semaphores=1: not found
It must be a valid shell script. I'm closing it because it is a user error. Don't hesitate to submit any new bug. ** Changed in: grub2 (Ubuntu) Status: New => Invalid -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/855242 Title: package grub-pc 1.99-12ubuntu4 failed to install/upgrade: ErrorMessage: 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/855242/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
