Troubleshooting

Creating a bug report/issue

I have searched the existing open and closed issues

Required Information

  • DietPi version | 9.15.2
  • Distro version | bookworm
  • Kernel version | Debian 6.1.140-1 (2025-05-22) x86_64 GNU/Linux
  • Architecture | amd64
  • SBC model | Native PC (x86_64)

Additional Information (if applicable)

  • Software title | Home Assistant
  • Was the software title installed freshly or updated/migrated? Freshly
  • Can this issue be replicated on a fresh installation of DietPi? Don’t know

Steps to reproduce

  1. Install Home Assistant from DietPi software
  2. Follow Home Assistant steps to install a Home Assistant Voice PE

Expected behaviour

  • Setup wizard should complete without errors

Actual behaviour

  • Setup fails when connecting device to Home Assistant server after checking for firmware updates. The wizard fails with message “The voice assistant is unable to connect to Home Assistant”.

Extra details

  • Searching for the error message above leads to posts in the Home Assistant forums that suggest the issue is with network configuration. However, inspecting the logs suggests the issues are with some missing system components, namely libpcap and ffmpeg.

On my system, the issue was fixed by running

sudo apt-get install python3-pcapy ffmpeg

Reporting this as a bug because the lack of these system packages hampers the user experience with Home Assistant in a way that is not obvious how to fix. Perhaps, these components should be installed along with Home Assistant.

The intention is not to pre-install every single package as we want to keep the system as lean as possible. It is difficult to predict which integration users will use with HA. Therefore we install a minimal version of HA in the first step. Additional packages must be installed later if required.
