I followed the instructions, and the apt-get said the installation completed successfully, but HASS still says when booting that it is not installed.
I used the manual raspberry pi installation instructions. Please help!
Not enough information. We need to see the message and what platform you are installing on to even guess what could be happening…
Most commom problem: you installed it with the wrong user.
Did you use a virtual_env or another user to install hass? What’s the log saying?
