Comment 4 for bug 1807226

After adding an ssh key to launchpad.com and doing launchpad-login, the branch command worked.

1. Add your ssh key to launchpad.com (~/.ssh/id_rsa.pub)
2. $ bzr launchpad-login your-fancy-username-here
3. $ bzr branch lp:whatever-you-where-trying-to-branch

Seems like after you do a login, the branch command uses ssh instead of http(s) and that did the trick.
