gitosis-init error | Traceback (most recent call last)

Hy Guys i got some error while setting up gitosis, i think its some kind of not installed python dependencies

here is my output

git@ubuntu-server ~ % sudo -H -u git gitosis-init < /home/git/cs8898_windows7_21.07.2014.pub
Traceback (most recent call last):
  File "/usr/local/bin/gitosis-init", line 9, in <module>

    return app.main()
  File "/usr/local/lib/python2.7/dist-packages/gitosis-0.2-py2.7.egg/gitosis/app.py", line 38, in main

  File "/usr/local/lib/python2.7/dist-packages/gitosis-0.2-py2.7.egg/gitosis/init.py", line 121, in handle_args
    user = ssh_extract_user(pubkey)
  File "/usr/local/lib/python2.7/dist-packages/gitosis-0.2-py2.7.egg/gitosis/init.py", line 39, in ssh_extract_user
    raise InsecureSSHKeyUsername(repr(user))
gitosis.init.InsecureSSHKeyUsername: Username contains not allowed characters: '----'

Would be nice to get some hints, i will try it my selfe too

This error comes from gitosis/init.py#L34-L39:

def ssh_extract_user(pubkey):
    _, user = pubkey.rsplit(None, 1)
    if ssh.isSafeUsername(user):
        return user
    else:
        raise InsecureSSHKeyUsername(repr(user))

That means the content of your pubilc key file isn't abcd...(long_key)...xxxxx= yourName, but includes at the end ----.

Sanitizes its content or regenerate your keys.
