No, this is because febootstrap in Ubuntu 12.04 is broken, which
prevents creation of the appliance.  You have to build febootstrap (at
least 3.14) by hand, install it, and then rebuild the appliance by
hand (update-guestfs-appliance).  This is explained in this email:

We have no Ubuntu maintainer, so Ubuntu just pull in the Debian
packages which they don't test and they don't work well.

libguestfs works best (indeed, is commercially supported) on Fedora
and RHEL.
