If I re-install over a system that was installed using 'guided: entire disk' partitioning and simply re-format the ext4 root partition as an xfs partition, the grub installation error does not re-occur.
The system still fails to boot, however, which seems to be a different bug (bug 856763). -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/855871 Title: Grub install fails after manual xfs partitioning To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/ubiquity/+bug/855871/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
