".../usr/sbin/grub-mkconfig: 35: /etc/default/grub: Syntax error: EOF in backquote substitution..."
Seems to be an error in /etc/default/grub, probably in line GRUB_CMDLINE_LINUX="acpi_osi=\"!Windows 2012\" I assume that there is a closing quote character missing. Try changing to GRUB_CMDLINE_LINUX="acpi_osi=\"!Windows 2012\"" -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1531794 Title: package grub-efi-amd64 2.02~beta2-9ubuntu1.7 failed to install/upgrade: subprocess installed post-installation script returned error exit status 2 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/grub2/+bug/1531794/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
