Jupyter crashes with segmentation fault - core dumped; help!

This is mysterious, as it's just started happening out of the blue, as it were.  I upgraded my system last on January 15, and everything was working fine; indeed I was using Jupyter happily yesterday.  But today, when I try to start it, either with `jupyter-lab` or `jupyter notebook` it crashes with `segmentation fault (core dumped)  jupyter notebook` (or whatever command I had entered).

A brief web hunt indicates that this is happening occasionally to people using other distros, or operating systems, and I've read that it may be due to some conflicting packages.  But I haven't changed, upgraded, or downloaded any packages since jupyter last worked.  It's just stopped working.  People on other forums have been advised to reboot (which seems to have no effect), or re-install, or revert to a previous version.  There are no discussions about this on the Archlinux jupyter package page.

What is going on, and how can I fix it?

Post the contents of the coredump https://wiki.archlinux.org/title/Core_d … _core_dump

On a guess you are running some non repo python stack (e.g. conda or packages from pip or so) that have changed in an incompatible way and are breaking the repo jupyter (or the reverse, non repo jupyter getting broken by system packages)

Re: Jupyter crashes with segmentation fault - core dumped; help!

Thank you - no, I'm pretty sure I'm only using packages from pacman.  I'll double check though, to make sure. 

Anyway, I did another system upgrade (`pacman -Syu` - which I should have done before posting), rebooted, and Jupyter starts again. 

I did have a look at the core dump, starting with `coredumpctl` (I had indeed been to the help page you linked) for a list, but I couldn't make much sense of it. 

Thank you again for your kind offer of help!
