Exactly the same issue. It starts since I did upgrade from 16.04.5 to 16.04.6. I attached the related config files: /etc/default/grub and /boot/grub/grub.cfg. My case is definitely not like #13: I have /boot entry in /etc/fstab and I double checked that when I do `update-grub' /boot is mounted, has free space and populated accordingly:
$ cat /etc/fstab| grep /boot # /boot was on /dev/sda7 during installation UUID=XXXX /boot ext3 defaults 0 2 $ df -h | grep /boot /dev/sda7 2.0G 125M 1.7G 7% /boot $ lsb_release -a No LSB modules are available. Distributor ID: Ubuntu Description: Ubuntu 16.04.6 LTS Release: 16.04 Codename: xenial I also tried #33 workaround: doesn't work for me. P.S. The most inconvenient thing for me in this is that I have a bluetooth keyboard as my primary keyboard, so now, since I did this upgrade, I have to keep another one physically attached keyboard each time when I want to boot. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1273764 Title: Grub ignores TIMEOUT options on /etc/default/grub To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/grub2/+bug/1273764/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
