I added ppa:ubuntu-mozilla-daily/ppa/firefox-aurora/ubuntu oneiric and ppa:banshee-team/ppa/ubuntu oneiric to my software sources, then did apt-get update. However, after selecting their specific sources from the menu in Software Center, the only packages available are language packs and extensions for Banshee and firefox-aurora. I had already uninstalled Banshee and Firefox.

If I try and install Banshee/Aurora with sudo apt-get it will install the old version. Searching for Banshee/Aurora in Software Center only shows the old version.

I'm guessing the packages in the PPAs conflict with the packages in the main sources. How do I install the newer versions?
