[This bug is targeted to the upcoming trixie release]

The package build-depends or depends on python3-pkg-resources, which is
deprecated upstream. Details can be found at

https://setuptools.pypa.io/en/latest/pkg_resources.html

Use of pkg_resources is deprecated in favor of importlib.resources,
importlib.metadata and their backports (importlib_resources, importlib_metadata).
Some useful APIs are also provided by packaging (e.g. requirements and version
parsing). Users should refrain from new usage of pkg_resources and should work
to port to importlib-based solutions.

Python 3.12 in unstable provides both importlib_resources and
importlib_metadata, so no additional dependencies on those packages are needed.

The psychopy package still uses the pkg_resources module.

Raising the severity of this issue. At the end of the
year 2025, raising the severity again to serious.

If the package is a namespace package, then please lower
the severity again to normal.

Should psychopy be removed from unstable ?

Updating to a new release seems a lot of work

Hi Alexandre,

The package builds in Git.  There are some issues when calling the
executable.  Yaroslav, can you help?

IMHO most of the work is actually done.  I somehow dropped the ball when
checking other RC bugs.  But I have the gut feeling we are nearly there.

Thank you for the ping anyway
   Andreas.

Hi Andreas and Alexandre,

NB recending via gmail for Alexandre...

I can try to help - I just need to float up a bit above current
monday flood of todos... hopefully wed. Any particular cut/paste of
outputs/pointers would be welcome, otherwise I will try to go from git.

I do not mind removing but I will be sad if Andreas had invested
time already, so would be a waste of HI (human intelligence) tokens ;),
so we can make a push to avoid that! ;)

Cheers,

Cheers,

Let me know if my team can be of any help on this, e.g. if there's anything
we can do on the repository side in order to make things easier for
packaging.

I should say that we've been moving away from the previous system of a
behemoth wxPython application (which was particularly hard to install on
Linux distros) towards:

   - more distinction between the psychopy *library* for running
   experiments in the users' own virtual env(s) and psychopy *app*
("Standalone"
   PsychoPy) which now has its own repo
   <https://github.com/psychopy/psychopy-app>. This was largely so that
   linux users, who more often just want the library, don't have to worry
   about wxpython as a dependency but the app is still available if they do
   - a complete rewrite of that wxpython app into electron/node, called
   PsychoPy Studio, which is available to Linux users as an AppImage
(e.g. AppImage
   for release 2026.2.4
   <https://github.com/psychopy/psychopy/releases/download/2026.2.4/PsychoPy_Studio_2026.2.4.AppImage>)
   but we could also talk about whether there are better ideas for
   distributing that app. The Electron app works differently - it's really
   easy for linux users to download and install and it then uses *uv* to
   set up Python virtual environments as needed in the users' home directory


Suffice to say, none of the PsychoPy team are packaging experts, but we're
happy to help out with whatever can help to make this less painful

Best wishes,
Jon

Package builds fine from Git in pbuilder but once you install the

I hope we can make the package a sensible citizen in Debian Med

Kind regards

That is the sort of thing my team might be able to help with. Is there
anything in
    ~/.psychopy3/last_app
?
