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