I can't reproduce this on the daily image (tried 20170208, to be precise). This was due to grub-common being in the seed rather than grub2-common; which lead to grub-pc not being on the livefs.
I'll mark this incomplete; if someone can reproduce this on a recent image, please mention it and include /var/log/syslog and /var/log/apt/* from the installer environment so we can see exactly what happens. ** Changed in: grub2 (Ubuntu) Status: Triaged => Incomplete ** Changed in: grub2 (Ubuntu) Importance: Critical => High ** Changed in: grub2 (Ubuntu) Assignee: (unassigned) => Mathieu Trudel-Lapierre (cyphermox) ** Changed in: grub2 (Ubuntu) Milestone: None => ubuntu-17.03 -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1639374 Title: grub-pc fails to remove, causing lubuntu installs to crash To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/grub2/+bug/1639374/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
