Troubleshooting installation problems

It can happen that you run into trouble while installing Home Assistant. This page is here to help you solve the most common problems.

pip3: command not found

This utility should have been installed as part of the Python installation. Check if Python 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 Home Assistant by running the following command instead:

python3 -m pip install homeassistant

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

No module named pip

Pip should come bundled with the latest Python 3 but is omitted by some distributions. If you are unable to run python3 -m pip --version you can install pip by downloading the installer and running it with Python 3:


No access to the frontend

In newer Linux distributions the access to a host is very limited. This means that you can’t access the Home Assistant frontend that is running on a host outside of the host machine.

To fix this you will need to open your machine’s firewall for TCP traffic to port 8123. The method for doing this will vary depending on your operating system and the firewall you have installed. Below are some suggestions to try. Google is your friend here.

For UFW systems (Ubuntu, Debian, Raspberry Pi OS, etc.):

sudo ufw allow 8123/tcp

For iptables systems (was the default for older distributions):

iptables -I INPUT -p tcp --dport 8123 -j ACCEPT
iptables-save > /etc/network/iptables.rules  # your rules may be saved elsewhere
