Installer crashes on partitioner

[Chris Jones]

Upon installation of Feisty Fawn Herd 2, when the installer gets to the partition setup, the installer crashes and an error displayed with the following details.

Traceback (most recent call last):
  File "/usr/lib/ubiquity/bin/ubiquity", line 185, in ?

I get the same error (more or less):

Also, it's a bit strange that I don't get to choose how to partition my disk. It seems to auto-select autopartition. I just hope it didn't screw up my other installation in this dual-boot system. I'll find out soon enough I guess. (Don't worry, I have backups) ;-)

I'll confirm it as I see it too.

Also, I don't know if this matters but in the machine that I try this on I have two disks, trying to install on the second one /dev/sdb. Or would have if the partitioner hadn't crashed.

[Chris Jones (foxmulder881)]

My test bed only has the one drive, so I don't think dual drives is the issue.

Thanks for your report. This is also bug 76976, since fixed; run 'sudo apt-get update; sudo apt-get install debconf ubiquity' in a terminal window before starting the installer to pick up the fix.
