Public bug reported: When installing from seed (haven't tried manual install), DM crypt and LVM, the grub install stage fails with the message:
grub install (something, something) failed: mapdevfs <path> Debugging, this is because the part that reads 'apt-install grub-common' outputs: Adding 'local diversion of /sbin/start-stop-daemon to /sbin/start-stop-daemon.REAL' Adding 'local diversion of /sbin/initctl to /sbin/initctl.REAL' this in turn is interpreted as input into $rootfs (calls findfs(), which calls grub_probe() which calls apt-install ...). This variable is then used by mapdevfs. But since the variable contains bogus data, grub-installer fails. Changing the relevant line in /usr/bin/grub-installer from: apt-install grub-common to apt-install grub-common > /dev/null Solves the problem (for me). ** Affects: ubuntu Importance: Undecided Status: New ** Tags: precise -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/913811 Title: grub-installer fails to install grub on new install To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+bug/913811/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
