Re: jupyter notebook immediately crashes with dead kernel




Solution 1:
sudo apt purge python3-ipykernel
sudo apt install python3-ipykernel

Solution 2:
OR, purge python-notebook package and install it again, it will automatically install ipykernel package while resolving its dependency.
sudo apt purge python-notebook
sudo apt install python-notebook

Should fix you're issue.

By the way, installing python-notebook from official debian repo(http://deb.debian.org/debian) works for me without a singal error.
