Hi folks,

After happily using psychopy on Windows machines for years I thought to give it a go on a linux machine.

Instructions followed as per [Installation — PsychoPy v2023.2.3](https://www.psychopy.org/download.html)

After install running psychopy on terminal produces the following error:

> $ psychopy  
> 23:14:22: Debug: Adding duplicate image handler for ‘Windows bitmap file’  
> 23:14:22: Debug: Adding duplicate image handler for ‘Windows bitmap file’

I found the following [Installing and running psychopy on Ubuntu 18.04 with conda python 3.6 · Issue #2082 · psychopy/psychopy · GitHub](https://github.com/psychopy/psychopy/issues/2082) regarding the libwebkitgtk library but

```auto
sudo apt-get install libwebkit[tab-completion]

```

outputs the following potential libraries

> libwebkit2gtk-4.0-37 libwebkit2gtk-4.0-dev libwebkit2-sharp-4.0-cil  
> libwebkit2gtk-4.0-37-gtk2 libwebkit2gtk-4.0-doc libwebkit2-sharp-4.0-cil-dev

(yes i did try to sudo install libwebkitgtk-3.0.so.0 but naturally found nothing)

Any guidance tips?

Many thanks  
Yiannis

P.S. The only thing I can think of is that my distro is Ubuntu19 and the latest wxPython wheel is for ubuntu18.04 which is the the one I installed…could that be it?

Hi,

I have the very same problem on a fresh Debian-10 (Buster) installation. Only libwebkitgtk2 is available, last with 1 was Stretch.

So i downloaded that oldstable libwebkitgtk-1.0-0\_2.4.11-3\_amd64.deb package, and the dependent libjavascriptcoregtk-1.0-0\_2.4.11-3\_amd64.deb as well, installed both without complains.

Then, `psychopy -c` started, but crashed:

> (psychopy:8598): Gtk-WARNING \*\*: 11:11:53.442: GModule (/usr/lib/x86\_64-linux-gnu/gtk-2.0/2.10.0/immodules/im-ibus.so) initialization check failed: GLib version too old (micro mismatch)

Hi,

Did anyone manage to find a solution? I have the same issue now trying to install psychopy on ubuntu 20.04.
