I encountered the same error with the i386 08-27 daily build, but I had first booted into the Live Desktop and updated ubiquity to version 2.3.9.
In my case the crash notification popped up almost immediately after selecting "Specify partitions manually (advanced)". I had not even clicked on Install Now yet. -- ubiquity crashed with UnboundLocalError in part_ask_option_changed() https://bugs.launchpad.net/bugs/625258 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
