I had the same problem. However, before I installed, I had to use GNU parted to partition my drive as both the Gnome Partition Editor and the installer claimed my drive was empty (it had an OS X installation on it). Now the installer and Gnome partition editor see my partitions, but these errors occur. The partition that OS X is installed to is HFS+ rather than HFS, I think this may be the Apple_Bootstrap partition mentioned in the first error message, so should I have installed OS X differently?
As for the 'Known Ubiquity issues in Ubuntu 6.06 LTS' link given earlier, I didn't set a boot strap partition on the mount points page, and I still get the errors mentioned above. Here is the 'installer crashed' report (/var/log/syslog was empty): Traceback (most recent call last): File "/usr/bin/ubiquity", line 130, in ? install(sys.argv[1]) File "/usr/bin/ubiquity", line 55, in install ret = wizard.run() File "/usr/lib/python2.4/site-packages/ubiquity/frontend/gtkui.py", line 266, in run self.process_step() File "/usr/lib/python2.4/site-packages/ubiquity/frontend/gtkui.py", line 755, in process_step self.mountpoints_to_summary() File "/usr/lib/python2.4/site-packages/ubiquity/frontend/gtkui.py", line 1114, in mountpoints_to_summary self.progress_loop() File "/usr/lib/python2.4/site-packages/ubiquity/frontend/gtkui.py", line 553, in progress_loop raise RuntimeError, ("Install failed with exit code %s; see " RuntimeError: Install failed with exit code 1; see /var/log/installer/syslog and /var/log/syslog ** Attachment added: "/var/log/installer/syslog" http://librarian.launchpad.net/4272172/syslog -- Failure to install bootloader on complicated PowerPC https://launchpad.net/bugs/48148 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
