Current Behavior

I try to install python3 and Pillow for OrcaSlicer via mods:

DOCKER_MODS: linuxserver/mods:code-server-python3|linuxserver/mods:universal-package-install
  INSTALL_PIP_PACKAGES: Pillow

But it fails to install:

Expected Behavior

If I try to install directly with command pip install Pillow --break-system-packages it works. My python code use from PIL import Image.

[LinuxServer-CI]

This issue has been automatically marked as stale because it has not had recent activity. This might be due to missing feedback from OP. It will be closed if no further activity occurs. Thank you for your contributions.

[aptalca]

Our universal mods currently support the alpine and ubuntu baseimages but orcaslicer is debian based.

[thespad]

The mod logic will handle Debian and it should broadly work where Ubuntu does but the Orcaslicer image doesn't setup a venv and the Kasm base installs python, so the pip install will break because of the Python system management changes in PEP 668. If there's a Debian repo package for Pillow you can install, that would work, but otherwise it would need changes to the image itself to change how it handles Python.

[aptalca]

For now you can set these env vars while we look into adding compatibility:

DOCKER_MODS=linuxserver/mods:universal-package-install
INSTALL_PIP_PACKAGES=Pillow
INSTALL_PACKAGES=python3-venv
CREATE_VENV=true

Thanks I try it and it works for now.
