I'm trying to install Mopidy Touchscreen but everytime I try it gives me this error:

You are using pip version 18.1, however version 20.0.2 is available.
You should consider upgrading via the 'pip install --upgrade pip' command.

When I try to upgrade pip it gives me the same error. I'm new to this kind of stuff so I hope anyone has an idea how to fix this.

Hi,
as the error sais "certificate verify failed", so you can try running pip with "--trusted-host files.pythonhosted.org".
See https://pip.pypa.io/en/stable/reference/pip/#general-options:

--trusted-host <hostname>¶
Mark this host or host:port pair as trusted, even though it does not have valid or any HTTPS.

Thanks, that works but now I have another problem. After trying to install Mopidy Touchscreen it gives another error with the final sentence:

Unable to run "sdl-config". Please make sure a development version of SDL is installed.

I found https://pypi.org/project/PySDL2/ and I tried to download a dev version of SDL but I can't download it with git. I tried to install that as well but it just says that it is unable to locate package.
