Just to follow-up on my last comment. I was unable to try the solution as grub would not see the Linux OS after a grub-install on /dev/sda, and omitting to run update-grub right afterwards. I struggled with a live-USB to fix grub, but after several hours, I ended just re-installing the whole thing.
After the new install the issue no longer appeared. I guess there is something flaky in the code that causes the issue to only appear on occasion. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/797544 Title: grub2 waits forever for keystroke before booting default OS. headless server. hang.
