Title:
  Cannot launch yubioath - throws Python ImportError

Status in yubioath-desktop package in Ubuntu:
  Fix Released
Status in yubioath-desktop source package in Xenial:
  New

Bug description:
  SRU:
  [Impact]
  The program lacks neccessary dependencies in order to start.
  The SRU adss these dependencies.

  [Test case]
  1. Install yubioath-desktop
  2. (Verify that python-pkg-resources is installed)
  3. Attempt to run yubioath from a terminal
  With python-pkg-resources in place, the program should start as expected.
  (Note that due to the nature of the program, it will almost immediately check for an USB key,  which it won't find if none is inserted.)
  4. Attempt to remove python-pkg-resources. Verify that this cannot be removed without also marking yubioath-desktop for removal.

  [Regression potential]
  Low. Dependencies are only added. These are the same ones used by newer versions of the package in for instance 17.04.


  Original report:

  Found on Ubuntu 16.04 Xenial Xerus amd64 running on Dell Latitude

  Launching yubioath does not start the application but aborts with the
  following error:

  $ yubioath
  Traceback (most recent call last):
    File "/usr/bin/yubioath", line 5, in <module>
      from pkg_resources import load_entry_point
  ImportError: No module named pkg_resources
