New issue by Sqvid on void-packages repository

https://github.com/void-linux/void-packages/issues/42793

Description:
### Is this a new report?

Yes

### System Info

Void 6.1.18_1 x86_64 GenuineIntel uptodate rrFFFFF

### Package(s) Affected

python3-jupyter_notebook-6.4.10_3

### Does a report exist for this bug with the project's home (upstream) and/or another distro?

_No response_

### Expected behaviour

After installing the package I would expect that `jupyter notebook` brings up the browser and allows me to create a new notebook with the python3 kernel.

### Actual behaviour

The browser opens but there is nothing listed under the "notebooks" option. [Picture example](https://imgur.com/a/ME8XWV9).

[Here is the output log.](https://pastebin.com/raw/4wKGtgN8) To me it looks like the `nbclient` package version needs to be `<0.6.0` but void packages `python3-nbclient-0.7.0_1`.

### Steps to reproduce

1. `# xbps-install -S python3-jupyter_notebook`
2. `$ jupyter notebook`
3. Switch to browser.

Comment:
it seems to work here
```
$ jupyter notebook 
[I 17:25:27.756 NotebookApp] Jupyter Notebook 6.4.10 is running at:
[I 17:26:08.080 NotebookApp] Creating new notebook in /Documents/Sage
[I 17:26:09.846 NotebookApp] Kernel started: a446b7da-859f-4817-bbb2-6fa70e41bf55, name: python3
[IPKernelApp] WARNING | debugpy_stream undefined, debugging will not be enabled
```
just to make sure: are we using Python 3 (ipykernel)?

Comment:
of course updating the ancient python3-jupyter_notebook may be a good idea anyway

Comment:
Can you install `python3-pip` (if you don't have it already) and run `pip3 check`? That should give an indication if it's a dependency issue or not.

Yes I all the packages are of the form `python3-*` and `python --version` is `Python 3.11.2`.

```
$ pip3 check
No broken requirements found.
```

```
$ pip3 check
ipykernel 6.19.2 requires debugpy, which is not installed.
ipywidgets 7.6.3 requires jupyterlab-widgets, which is not installed.
nbconvert 6.4.5 has requirement nbclient<0.6.0,>=0.5.0, but you have nbclient 0.7.0.
```

I managed to also get it working. Im not exactly sure how but in the process of messing it around i think I've possibly removed a pip package that may have caused the trouble. `pip3 check` still complains with the aformentioned messages but it works. I don't know why the `nbclient` version is no longer a dealbreaker though.

EDIT:
I've found the conflict. the package `yt` installed via `pip install yt` is what breaks it. Not sure whether this should be treated as a problem with `yt` or whether void's jupyter dependencies are just very outdated. For now I will just install both via `pip` since I need both working.

Comment:
Yeah it's quite old, I have been using it via pipx too. I plan to update it when they land the big update of notebook-v7.
