Can't resolve dependencies on Ubuntu 19.04
I'm trying to install opensesame on Ubuntu 19.04. I first tried with pip (`pip install python-opensesame`), and I was able to install the main program this way, but there were uncountable problems with dependencies, so I uninstalled it with pip.
I then added `ppa:smathot/cogscinl` and tried using apt. Install failed with a huge list of dependencies that weren't going to be resolved (apt rarely has this problem in my experience -- it's normally excellent with dependencies). So I tried with Synaptic, which is even better. And I got this:
opensesame: Depends: python-qdatamatrix but it is not going to be installed Depends: python-qprogedit but it is not going to be installed Depends: python-qnotifications but it is not going to be installed Depends: python-pseudorandom but it is not installable Depends: python-pygame but it is not going to be installed Depends: python-webcolors but it is not going to be installed Depends: python-markdown but it is not going to be installed Depends: python-pyqt5.qtwebkit but it is not going to be installed Depends: python-pyqt5.qtsvg but it is not going to be installed Depends: python-fileinspector but it is not installable Recommends: python-imaging but it is not installable Recommends: expyriment but it is not installable Recommends: psychopy but it is not going to be installed Recommends: pyaudio but it is not installable Recommends: python-pygaze but it is not installable Recommends: ipython-qtconsole but it is not going to be installed Recommends: python-shapely but it is not going to be installed
Jesus. The weird thing is that I was indeed able to install most of these dependencies manually, one by one, in Synaptic. But alas, I can't install all of them. This is where I'm currently at:
opensesame: Depends: python-pseudorandom but it is not installable Depends: python-fileinspector but it is not installable Recommends: python-imaging but it is not installable Recommends: expyriment but it is not installable Recommends: psychopy but it is not going to be installed Recommends: pyaudio but it is not installable Recommends: python-pygaze but it is not installable Recommends: ipython-qtconsole but it is not going to be installed Recommends: python-shapely but it is not going to be installed
Neither `python-pseudorandom` nor `python-fileinspector` are available to install. Searching for them turns up nothing.
`python-imaging` also does not exist, but `python-imaging-doc-html` and `python-imaging-doc-pdf` do exist. I do have `python-pil` installed, which says it's the "pillow fork" of the python imaging library. But if that's what I need, it's not being recognized as such.
`python-expyriment` is installed, but I'm told it's not in the message above, which calls it `expyriment`, which is not available.
`psychopy` is installed, but I'm told it's not.
`python-pyaudio` is installed, but the message above wants `pyaudio`.
And so on... This is a hell of a mess. Where do I go from here?
