apt-get install grub2 updated the grub2 package to 1.97~beta3-1ubuntu8. This appears to have fixed the problem, i.e. I ran
grub-install /dev/sda and then changed the value of GRUB_HIDDEN_TIMEOUT back to 0 (the package default) GRUB_HIDDEN_TIMEOUT=0 ran grub-update, and the machine still boots through as it should. One very odd thing: the other grub2 packages still report being at version 1.97~beta2-2ubuntu2 ? This must be a mistake, given that grub2 is just a dummy package. ibis:~~$ dpkg -l | grep grub ii grub-common 1.97~beta2-2ubuntu2 GRand Unified Bootloader, version 2 (common ii grub-pc 1.97~beta2-2ubuntu2 GRand Unified Bootloader, version 2 (PC/BIOS ii grub2 1.97~beta3-1ubuntu8 GRand Unified Bootloader, version 2 (dummy p -- Default grub2 configuration won't boot through to default OS https://bugs.launchpad.net/bugs/428570 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
