The bzr-beta-ppa Ubuntu PPA for Beta Users has moved

As the final step of consolidating all of the official Bazaar PPAs on Launchpad under one Launchpad team, the Bazaar Beta PPA formerly found at https://launchpad.net/~bzr-beta-ppa/+archive/ppa has moved to live under the main ~bzr team at https://launchpad.net/~bzr/+archive/beta. If you are a user and tester of Bazaar beta releases via this PPA, you will need to update your APT sources.list lines –  you can see the new sources.list lines under the “Technical details about this PPA” section at the above link.
