pip3: command not found

This utility should have been installed as part of the Python 3 installation. Check if Python 3 is installed by running python3 --version. If it is not installed, download it here.

If you are able to successfully run python3 --version but not pip3, install KS Assistant by running the following command instead:

python3 -m pip install homeassistant==2025.3.4

On a Debian system, you can also install python3 by sudo apt-get install python3 and pip3 by sudo apt-get install python3-pip.

If you run into errors during installation, check that you’ve installed all the necessary prerequisite packages, which include python3-dev, libffi-dev, and libssl-dev. On a Debian-based system, you can install these via apt-get:

sudo apt-get install python3-dev libffi-dev libssl-dev
