Comment 1 for bug 1314686

I think this issue can be fixed by
1. make utopic packages for 1.18.1 in the stable ppa
2. run assemble-public-tools for 1.18.1 again
3. publish the tools
4. tell streams.canonical.com to publish 1.18.1

But how do the packages in ports become tools? The assembly script knows utopic is the devel series, and series-ambiguous package will be classified as a utopic tool. so streams.canonical.com might make new tools using the old packages.
