OpenSesame builder/GUI on Linux

adkinsty

I tried installing OpenSesame on my linux box using both pip and Cogsci.nl PPA. After doing so, however, I couldn't find the builder app. Furthermore, when I tried to run an open sesame file without the GUI, using the opensesame command, I get the following error: qtpy.PythonQtError: No Qt bindings could be found

Does anyone know how to address this error? Also, is it possible to use the builder on Linux? If so, how do I do this?

Hi Tyler,

Installing OpenSesame just from the PPA is fine! Pip installing it as well doesn't hurt in principle—but it can make things very confusing.

OpenSesame should run straight away, so something is funky here. What distribution and version of Python are you using exactly? And could you post the full stacktrace?

Cheers,
Sebastiaan

Ok. I just deleted everything and retried the install using the PPA. After typing sudo add-apt-repository ppa:smathot/cogscinl, everything seems fine. However, after typing sudo apt-get update I get the following warnings:

Err http://us.old-releases.ubuntu.com quantal Release.gpg

Then when I type sudo apt-get install opensesame I get the following message:

Some packages could not be installed. This may mean that you have requested an impossible situation or if you are using the unstable distribution that some required packages have not yet been created or been moved out of Incoming.

The following information may help to resolve the situation:
The following packages have unmet dependencies:

E: Unable to correct problems, you have held broken packages.

SO, it seems that I just have a bunch of unmet dependencies. Do you think I should try to install/update each of these things?

Hi Tyler,

Can you install any other packages on your system? I had the same thing recently. Some PPA were not available any more (404 errors) and that made it impossible to install or update any other packages, even if they did not depend on the PPAs that were missing. Could you try to resolve the PPA issues and try install Opensesame again?

This link might help: http://askubuntu.com/questions/758653/launchpad-packages-not-found-upon-update

(PS run sudo apt-get update to identify the broken ppas)

Good luck,

Eduard

You're running Ubuntu 12.10 (Quantal Quetzal)! This is a very old distribution for which support ended in 2014—official support by Ubuntu, I mean.

I would definitely upgrade your system, because right now you're not even receiving security updates anymore. Once you've upgraded, you can just install OpenSesame from the PPA.

If you want to stick to 12.10, then running OpenSesame may be tricky.
