Comment 16 for bug 1015207

If there is no ubuntu user, then the install actually failed. The logs for that are in /var/log/maas/rsyslog you might be able to find some errors in the installation. The fact that you edited the preseed with regard to the ubuntu user, and the ubuntu user didn't get created seem likely to be related.

Also, /var/lib/cloud on server02 would likely be useful. I'd like to see what is in /var/lib/cloud/instance/scripts. but the whole thing would be nice to have attached.
