The user name xiezhiwei is not registered on Launchpad.

when i "bzr launchpad-login xiezhiwei",I have registered any SSH keys with Launchpad.

https://launchpad.net/~289444068-w is the url to your launchpad identity where indeed your registered an ssh key.

So you should either:

- change your lauchpad id or
- use 'bzr launchpad-login 289444068-w'

@Vincent Ladeuil ,thank you~
but when I do "sudo bzr branch lp:openstack-dashboard".It reminds me as follows:
The authenticity of host 'bazaar.launchpad.net (91.189.90.11)' can't be established.
RSA key fingerprint is 9d:38:3a:63:b1:d5:6f:c4:44:67:53:49:2e:ee:fc:89.
Are you sure you want to continue connecting (yes/no)? yes
Warning: Permanently added 'bazaar.launchpad.net,91.189.90.11' (RSA) to the list of known hosts.
Permission denied (publickey).
bzr: ERROR: Connection closed: Unexpected end of message. Please check connectivity and permissions, and report a bug if problems persist.
appreciated~

This is an ssh/launchpad issue, not a bzr one :)

The relevant line here is:
  Permission denied (publickey).

You can debug it without involving bzr by doing:

   ssh -vv bazaar.launchpad.net

this should give you enough hints about what is used to connect and what is wrong then.

'man ssh_config' will also gives you ideas about how to specify which key you want to use for which host.

For example, I put the following in my ~/.ssh/config:

Host *.launchpad.net
     IdentityFile ~/.ssh/vila@launchpad

So the 'vila@launchpad' key is used whenever I conect to any host in the launchpad.net domain.

how can I get my ID?

Your ID is your launchpad login (the one you used to post this comment) so it appears below:
