Answer 1

If above are not working, please try this it works(I had similar situations and this works):

1. download get-pip.py: curl https://bootstrap.pypa.io/get-pip.py -o get-pip.py

2. Run the downloaded file: python get-pip.py

   Above uninstalls the old version and install the latest ones. Reference Link: https://pip.pypa.io/en/stable/installing/#installing-with-get-pip-py
