Installation of Jupyter Notebook

Are you able to copy and paste the text of the error message?

If you can, please copy and paste everything that is shown as an error message, and show it like code, following the instructions in the pinned thread. Otherwise, please show a screenshot. It does not make any sense right now that what you have shown is complete (it should not end with :, that makes it look like there should be more after it).

Please also clearly explain the steps that you take in order to try to “open jupyter notebook on the laptop”.
