Issue
In Debian 11 I had installed jupyter lab with pip in my user directory, but on Debian 12 this is not possible anymore since href="https://www.debian.org/releases/stable/i386/release-notes/ch-information.en.html#python3-pep-668" rel="nofollow noreferrer">Debian decided to follow pep-668 and python packages are marked as externally managed, you can only install system wide with the package manager (APT).
I installed python3-jupyterlab-server lab with APT, but it fails to start
$ sudo apt reinstall python3-jupyterlab-server ... ... Preparing to unpack .../python3-jupyterlab-server_2.16.5-1_all.deb ... Unpacking python3-jupyterlab-server (2.16.5-1) over (2.16.5-1) ... Setting up python3-jupyterlab-server (2.16.5-1) ... $ jupyter lab Traceback (most recent call last): File "/usr/local/bin/jupyter-lab", line 5, in <module> from jupyterlab.labapp import main ModuleNotFoundError: No module named 'jupyterlab'I installed Jupyter Lab with pip in a virtual environment and can successfully start it from there. Is this the only way?
I understand the value of virtual environments or conda for maintaining a lot of data analysis packages. But Jupyter Lab is now a core component of the system, so I guess it should be installed system-wide with the system package manage (APT on Debian). I'm wondering what's wrong in my config, why can't I start jupyter lab when installed from apt?

Solution
Have you tried installing pipx via apt and then installing it via pipx install jupyterlab?
It is an alternative way of installing packages mentioned in the first link.
