There currently is no easy way to fix this.

I assume you have `python3-jupyter` installed. The dependencies `python3-jupyter_console` and `python3-ipython` where switched from `python3-prompt_toolkit1` to `python3-prompt_toolkit2`.

The simplest workaround would be to remove `python3-jupyter` and all dependencies with `xbps-remove -R python3-jupyter`, then make sure `python3-prompt_toolkit1` isn't installed anymore, update your system and reinstall `python3-jupyter`.
