Title:
  python-paramiko in trusty is incompatible with OpenSSH in vivid

Status in paramiko package in Ubuntu:
  Won't Fix

Bug description:
  When attempting to connect to a vivid host from a trusty client, I get
  the following traceback:

  Traceback (most recent call last):
    File "test_script.py", line 6, in <module>
      client.connect("10.0.3.179", username='ubuntu', password='password')
    File "/usr/lib/python2.7/dist-packages/paramiko/client.py", line 306, in connect
      t.start_client()
    File "/usr/lib/python2.7/dist-packages/paramiko/transport.py", line 465, in start_client
      raise e
  paramiko.SSHException: Incompatible ssh peer (no acceptable kex algorithm)

  The commit that fixes this in paramiko is
  e7f41de2f2dac5d03404f35edc5514f12e42c49f (git bisect FTW), which was
  only released in 1.15 (1.15.1 is in utopic and vivid).

  Modifying the attached script to point at a vivid host and running it
  on a trusty machine should reproduce.
