Comment 7 for bug 709363

So that's clearly ended up as not swap. I'm entirely unsure how this has happened though, even after reading through your logs.

Are you by any chance able to reproduce this? If so, can you add a 'set -x' to the top of /lib/partman/lib/base.sh before you get to the partitioning page, and run the installer in debug mode ("Try Ubuntu", then 'ubiquity -d'). Please attach the new logs once you have done this.

Thanks!
