termios.error: (5, 'Input/output error') on xonsh appimage with prompt_toolkit 3

[anki-code]

Hello!

When I try to run xonsh.AppImage from bash I get the error termios.error: (5, 'Input/output error'). Could you please help to understand the cause?

5 minute way to create xonsh.AppImage and reproduce on linux:

mkdir -p /tmp/test && cd /tmp/test
git clone https://github.com/niess/python-appimage && cd python-appimage
echo -e "git+https://github.com/xonsh/xonsh\nprompt_toolkit\nPygments" > applications/xonsh/requirements.txt 
python -m python_appimage build app applications/xonsh

After it run from bash:

./xonsh-x86_64.AppImage --shell-type ptk3
@ echo 123

As result:

Stopped xonsh-x86_64.AppImage

Xonsh encountered an issue during launch
Failback to /bin/sh

Could you please help or give an advice how I can debug this and find the cause?

I noticed that this error appears when I run xonsh.AppImage from bash. If I install xonsh locally, run it and then run xonsh.AppImage from xonsh it works without errors.

Thanks!

I'm not familiar with AppImages. Could it be that they don't allocate a pseudo terminal, or a pseudo terminal with different properties somehow?

Thank you for response! Is there a way to check it?

hi @jonathanslenders! We have the second issue around this (link above). How we can debug this?
