So, after some trial-and-error, I managed to install Jupyter and its key GUIs (notebook and lab) using pip3. The jupyter notebook and the jupyterlab applications load fine. Whenever I try to create or access a notebook, however, the kernel is DOA. I tried restarting it without any luck. This is regardless of what language this kernel corresponds to (so it's not a language-specific problem). I encounter a similar question where the solution was ownership of the files in a certain folder, so I made sure that I maintain ownership of these files with my usual user (not root). Still, the problem persists. If you have any ideas as to how to resolve it, I'd be grateful. Cheers
Here is the error message I get, BTW:
