Ubiquity often tells you to file bugs against it when things go wrong. Sadly, it's difficult for someone to determine which part of the installation process is failing. We try to sort bugs into the right place.
Of course, adding documentation is a good thing, but there really isn't an official document that describes this adequately. You may wish to edit http://ubuntuguide.org/wiki/Dapper and add this information there. Thanks. ** Changed in: ubiquity (Ubuntu) Status: Unconfirmed => Fix Released -- Unobvious where to report Ubuntu installation problems https://launchpad.net/bugs/57189 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
