My computer does not have network connectivity and I need to install dnspython as explained in here

So I

• Downloaded the dnspython-2.6.1.tar.gz
• Tried to install using: pip install dnspython-2.6.1.tar.gz

The installation fails because it is unable to install hatchling. Here is the output:

# /opt/VRTSnas/python/venv/bin/pip install hatchling-1.24.2.tar.gz

  note: This error originates from a subprocess, and is likely not a problem with pip.

But if I check on another computer for dependencies, the dnspython package does not seem to require hatchling

pip show dnspython

I tried to download hatchling-1.24.2.tar.gz and pip install but it further seems to depend on a package named pluggy

Any tips to resolve this issue?
