Unable to detect Python kernels in VS Code Jupyter notebooks after migrating from Windows 11 to Arch Linux

### Environment Details - **Previous OS**: Windows 11 - **Current OS**: Arch Linux - **Desktop Environment**: KDE Plasma - **IDE**: Visual Studio Code (**OSS CODE**) - **Required Feature**: Jupyter Notebook support ## Issue Description After migrating from Windows 11 to Arch Linux, I'm unable to get Jupyter notebooks working in VS Code. Specifically, VS Code cannot detect any Python kernels for the notebooks, preventing me from running any code. ## What I've Tried ### Attempt 1: Direct Installation First, I attempted to install Jupyter directly using pip:

pip install jupyter --break-system-packages

This resulted in an error about externally managed environment, which is expected behavior in Arch Linux. ### Attempt 2: Virtual Environment Setup Then I tried setting up a virtual environment:

python -m venv .venv
source .venv/bin/activate
pip install jupyter

This is the result I got:

[harshal@quanta ~]$ python -m venv .venv
[harshal@quanta ~]$ source .venv/bin/ativate
bash: .venv/bin/ativate: No such file or directory
[harshal@quanta ~]$ ls
Desktop  Documents  Downloads  Music  Pictures  Public  sof-bin  Templates  Videos  yay
[harshal@quanta ~]$ source .venv/bin/activate
(.venv) [harshal@quanta ~]$ code .
(.venv) [harshal@quanta ~]$

**Code** : ### Attempt 3: System Package Installation I also attempted to install through pacman:

sudo pacman -S python-jupyter

This failed with "target not found: python-jupyter" error. ### Output of ls -al .venv

## Current State Even after these attempts, VS Code still cannot detect any Python kernels for Jupyter notebooks, as shown in the screenshot below: ## System Configuration - VS Code has the Python extension installed - Python is installed and accessible from terminal - Virtual environment is created but not being detected by VS Code ## Expected Behavior VS Code should be able to: 1. Detect the Python interpreter in the virtual environment 2. List it as an available kernel for Jupyter notebooks 3. Allow running notebook cells using the selected kernel ## Actual Behavior - No kernels are being detected - Cannot run any notebook cells - Kernel picker shows no available kernels ## Question How can I properly configure VS Code to detect and use Python kernels for Jupyter notebooks on a fresh Arch Linux installation, considering the system package management restrictions?
