First installation and Conda is not working correctly. Error (699)

Question

First time when I downloaded Anaconda and tried to install scikit-learn (version 0.24.2) in my own environment I realized that it is not checking but installing through Anaconda Navigator. Then I tried to install it manually with help of cmd and conda.exe (conda install -n DeepLearning scikit-learn) and started to get super strange errors, which I can't find in Google.

I decided to do some work that can help, install Conda on C (SSD) and not installing anything but just update all libraries (conda update --all) as scikit-learn is always being installed not up to date. And that is what I am getting:

ERROR conda.core.link:_execute(699): An error occurred while installing package 'defaults::scikit-learn-0.24.2-py38hf11a4ad_0'.

I've tried almost everything and do not know what to do. Please, help me.

P.S. I haven't encoded anything it is how it looks like. Screen of cmd

The issue is caused by the conda installation/update script incorrectly pass in path of "C:\Anaconda\Menu\notebook.json" as "C:\Anaconda\Menu\notebook.jso". Even if you fix this error, the next error it is going to complain is "C:\Anaconda\Menu\anaconda-navigator.jso"

The workaround is:

1. Navigate to C:\Anaconda\Menu\
2. Rename notebook.json to notebook.jso
3. Rename anaconda-navigator.json to anaconda-navigator.jso
4. Rerun conda installation/update
5. Revert step #2 and #3 once #4 is successful
