Boot live session - selecting 'Try Ubuntu' option. b. Open nautilus and mount a partition (happened to be /home) c. Start install Ubuntu. Previous workarounds did not seem to help e.g. CLI ubiquity --debug, starting gparted then closing. I hope it gets fixed before release as having an OS not able to install from its media is not a great selling point for new users :-( -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1080701 Title: After 'Preparing to install Ubuntu' screen, raring installation hangs To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/ubiquity/+bug/1080701/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
