Comment 15 for bug 1066347

I booted a 12.04.2 disc and installed the apt-clone version from precise-proposed then choose to upgrade my Oneiric system to Precise. I inspected the contents of /target/ubiquity-apt-clone/apt-clone-state-ubuntu.tar.gz and confirmed that /etc/apt/sources.list was in there and that the path was correct.

Later on I received a crash from apt-clone but that was due to the package installed on my system and uncorrectable problems.

Subsequently, I considered this verification done for precise.
