error while installing python3

[ved prakash]

please help me to short out the following error I got while installing PYTHON3 LIBRARY in UBUNTU 20.4 in windows 10.

Dear prakash,

This problem is caused because pip can not trust the url (https://pypi.org) to retrieve requested data. You can work around this problem by adding a certificate or temporary declaring that url as a trusted one. the first approach is more secure, but the second one is easier. THIS link contain more information about both approaches.

For the easier approach, you can do as in mentioned link encouraged:

pip install --trusted-host pypi.org --trusted-host pypi.python.org --trusted-host files.pythonhosted.org <packageName> -vvv
