Troubleshooting

• My package manager is working and not locked by another process.
• If prebuilt wheels failed, I tried installing with --build-wxpython to build from source.
• I made sure /tmp has enough disk space during the build process.
• I have reviewed the log file (path shown in the terminal) for details on the error.
• I've searched existing GitHub issues to make sure this problem hasn’t already been reported or resolved.

Describe the bug

Hi!
I am using the GUI installer in Linux Mint 22 Cinnamon and after the installer I open the builder and I get the following error.

I have tried many options: modify the devnames.pop, install it again using pip, tried it in Ubuntu 22.04 and 24.04 and I always get the same problem.

Any ideas on how to solve it?
THANKS!

Operating System

Linux Mint 22

Install command used

bash <(curl -LsSf https://github.com/wieluk/psychopy_linux_installer/releases/latest/download/psychopy_linux_installer) --gui
