Comment 8 for bug 1462001

Hi Robie.

I updated the source package to include distro-info in build-depends.
    lp:~sinzui/ubuntu/wily/juju-core/juju-1.22.5

This ensure juju can learn about every Ubuntu distro that is know to the host system. I think this addresses the case where Ubuntu chooses to rebuild an old package. After verifing it myself, I also sent it to Lp to confirm
