*** This bug is a duplicate of bug 47848 *** Thanks for your report. Due to some reliability problems with GRUB and XFS, you need to use a non-XFS root filesystem or create a non-XFS /boot filesystem. Bug 47848 is filed to note that the partitioner should warn you about this up-front.
(This is an educated guess - although I think a fairly reliable one - because you only provided part of /var/log/installer/syslog rather than the whole file. In future, I would prefer to have the whole file.) ** This bug has been marked a duplicate of bug 47848 should warn at partitioning stage if /boot is on XFS -- installer crashed https://launchpad.net/bugs/52586 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
