bzr push questions on server guide

[lars nooden]

This is my first time using bzr.  I'm trying to follow the
instructions for editing the server guide:

https://wiki.ubuntu.com/DocumentationTeam/SystemDocumentation/UbuntuServerGuide

But I am getting errors when trying to push my changes:

$ bzr push lp:~larsnooden/serverguide/serverguide-review-6.1
You have not informed bzr of your Launchpad ID, and you must do this to
write to Launchpad or access private data.  See "bzr help launchpad-login".
bzr: ERROR: Invalid url supplied to transport:
"bzr+ssh://bazaar.launchpad.net/~larsnooden/serverguide/serverguide-review-6.1":
no supported schemes

After I use bzr whoami, the error changes:

$ bzr push lp:~larsnooden/serverguide/serverguide-review-6.1
Permission denied (publickey).
ConnectionReset reading response for 'BzrDir.open_2.1', retrying
Permission denied (publickey).
bzr: ERROR: Connection closed: Unexpected end of message. Please check
connectivity and permissions, and report a bug if problems persist.

How do I move the changes I have made to my Launchpad Account?
