This is just me stumbling around. but when I install followed the Linux instructions inside a conda environment, that is use pip to install psychopy,
conda create --name psychopy python=3.6 pip
conda activate psychopy
pip install psychopy psychtoolbox
# download wxPython from https://extras.wxpython.org/wxPython4/extras/linux/gtk3/ into ~/Downloads
pip install ~/Downloads/wxPython-4.0.7.post2-cp36-cp36m-linux_x86_64.whl
I got a new useful error message (note also that lack of errors about gtk2 etc.)
09:32:46 AM: Debug: Adding duplicate image handler for 'Windows bitmap file'

ImportError: libwebkitgtk-3.0.so.0: cannot open shared object file: No such file or directory
Ah! Missing libwebkitgtk-3.0
sudo apt install libwebkitgtk-3.0-dev
Starting psychopy still gives warnings about Windows bitmap file, but I am able to login!
Other note, the provided psychopy-env.yml file still seems to be missing a few packages (in particular, libwebkitgtk-3.0-dev to allow login, but also overlay-scrollbar-gtk2, libatk-adaptor, libgail-common, and libcanberra-gtk-module). The full list of packages in an environment created with the provided .yml is copied below (conda list -n psychopy). I admit that I don’t know what rules conda uses for determining when to use system packages like libwebkitgtk-3.0-dev. But I suppose this all suggests that conda can sometimes prevent the use of packages which were installed with sudo apt, while an environment is activated (e.g., libwebkitgtk-3.0-dev is accessible when the environment is created manually but not when created with the current psychopy-env.yml)? Or maybe there’s a mismatch between the versions of one of the packages that I get with pip vs conda?
