In the future, post exactly what you did. And the logs.
Now if i have to use my crystal ball, i see 2 of the dependencies are missing (python-traitlets and python-tornado) and since these are handled automatically, it leads to the conclusion you did not install from the repos and at that point even my crystall ball is helpless: where did you get it from, how did you install etc. is a total mystery. But in any case, if you compile or install stuff manually, it is your problem to know which dependencies are needed.
package is from extra/jupyter-notebook
this deps should be handled:
Depends On : jupyter-notebook-shim jupyter-server jupyterlab python python-jupyter-client python-jupyter-core python-jupyterlab-server python-tornado python-traitlets
I don’t know what this is or what to do with it - but I can install it without issue
and after that, start two different applications from the menu (JupyterLab and Jupyter Notebook) which both open a browser and … then I don’t know what to do with it.
But there is no error that I can see.
To install it I did: sudo pacman -Syu jupyter-notebook
My system was fully updated so only the needed dependencies (many) where fetched.
LANG=C sudo pacman -Syu jupyter-notebook
