PermissionError when writing kernel connection file #23124
Comments

Fixed :) changed permission setting and was able to run both spyder and jupyter now! |

Yep, that was the issue. Glad you were able to figure it out on your own. |

Sorry, after a second thought, I think we can improve the user experience by providing a sensible error message when this happens. We'll address that in 6.0.4, to be released at the beginning of next year. |
