Well, that particular failure is unrelated to grub -- it's caused by systemd updates which fail the installation while all packages aren't up to date on the mirrors being used.
I've noticed the fix is on the upstream git as well as in Debian; we'll get it in Ubuntu shortly. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1459706 Title: Ubuntu 15.10 daily ISO installation fails to reboot with Program Exception To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/grub2/+bug/1459706/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
