No matching distribution found for cherrypy message is displayed while installing cherrypi.

Issue

Below is the error message that I am receiving while installing Cherrypi python package,

pip3 install cherrypy
WARNING: Running pip install with root privileges is generally not a good idea. Try `pip3 install --user` instead.

Checking the issue from the above error message, “Failed to establish a new connection” is something that I looked at and then I tried to download a Cherrypi wheel package directly to see if I can download or not.

No matching distribution found for cherrypy is also coming up at the end of the message.

Below is the error message while trying to download the wheel file directly. Even that also failed with error message.

wget https://files.pythonhosted.org/packages/9e/89/e333e597c090d12d3a0d208f751366da7db8c44c8b392b467dd993366e53/CherryPy-18.6.1-py2.py3-none-any.whl

Resolving files.pythonhosted.org (files.pythonhosted.org)... failed: Name or service not known.
wget: unable to resolve host address ‘files.pythonhosted.org’

Even a direct clone of Cherrypi package was also not working.

Resolution

Upon looking at the error message, we can see that wget is not working, and looks like there is a network issue while downloading the package.

Update resolv.conf file with nameserver 8.8.8.8 and then try to download the package.

Navigate to /etc/ directory and update resolv.conf file with the above nameserver parameter and then try to download the file as well as install the package.

Upon updating the resolv.conf file, I was able to install the package successfully.

A direct package can be searched and downloaded from here.
