Package: pyhoca-gui
Version: 0.5.0.6-0.0


While the x2goserver and x2goclient packages are running fine on my machines (server: OpenSUSE Leap 42.1, client: OpenSUSE 13.2), the pyhoca-gui package can't be installed from the x2go repository:
http://packages.x2go.org/opensuse/13.2/main/x86_64/

The same applies to the version in the heuler repository which contains nightly builds, as far as I understand. In both cases the package carries a dependency on python-wxWidgets-2_9 which can't be fulfilled by the OpenSUSE repositories; these offer only the 3_0 and alternatively the 2_8 packages.

The OpenSUSE Build service version (which is some minor versions behind the current ones on the x2go project server) actually has a 3_0 dependency (instead of 2_9) and can be installed:
http://download.opensuse.org/repositories/X11:/RemoteDesktop:/x2go/openSUSE_13.2/

But: this version refuses to run. When started from a terminal command line, it throws these errors:

ak@tantalus:~> pyhoca-gui
Traceback (most recent call last):
  File "/usr/bin/pyhoca-gui", line 35, in <module>
    from pyhoca.wxgui.launcher import PyHocaGUI_Launcher
  File "/usr/lib/python2.7/site-packages/pyhoca/wxgui/launcher.py", line 38, in <module>
    from x2go import X2GOCLIENT_OS
  File "/usr/lib/python2.7/site-packages/x2go/__init__.py", line 189, in <module>
    from defaults import X2GOCLIENT_OS
  File "/usr/lib/python2.7/site-packages/x2go/defaults.py", line 388, in <module>
    RSAHostKey = paramiko.RSAKey.generate(RSAKEY_STRENGTH)
  File "/usr/lib/python2.7/site-packages/paramiko/rsakey.py", line 156, in generate
    public_exponent=65537, key_size=bits, backend=default_backend()
  File "/usr/lib64/python2.7/site-packages/cryptography/hazmat/backends/__init__.py", line 35, in default_backend
    _default_backend = MultiBackend(_available_backends())
  File "/usr/lib64/python2.7/site-packages/cryptography/hazmat/backends/__init__.py", line 22, in _available_backends
    "cryptography.backends"
AttributeError: 'EntryPoint' object has no attribute 'resolve'

Which leads to the situation, that pyhoca-gui can't be run on OpenSUSE at the moment. Which I regret.

Best regards
Albrecht Kolthoff
