[BUG] Missing salt-ssh dependencies on Ubuntu 16.04

Description Following the upgrade of my salt client from 3000.3+ds-1 to 3001+ds-1 I started getting the following error.

$ salt-ssh '*' test.ping
Traceback (most recent call last):
  File "/usr/bin/salt-ssh", line 5, in <module>
    from pkg_resources import load_entry_point
  File "/usr/lib/python3/dist-packages/pkg_resources/__init__.py", line 2927, in <module>

    raise DistributionNotFound(req, requirers)
pkg_resources.DistributionNotFound: The 'pycryptodomex>=3.4.7' distribution was not found and is required by salt

Setup Start Ubuntu 16 desktop/server (haven’t tested any other os) Add the salt repo http://repo.saltstack.com/py3/ubuntu/16.04/amd64/latest sudo apt-get install salt-ssh

Steps to Reproduce the behavior salt-ssh '*' test.ping

You can fix the issue by running: sudo apt-get install python3-pycryptodome

Expected behavior The salt-ssh or salt-common package should include python3-pycryptodome as a dependency so it is installed by default.

Just to confirm this fix has worked for me.

My test process was salt-ssh 'target' test.ping

My set-up process is the same as @RobHooper I’m on 3001+ds-2 and python3-pycryptodome was installed when I updated to it.

[RobHooper]

python3-pycryptodome is available for 16.04 from the salt stack repositories.
