Matplotlib created a temporary config/cache directory

[vrabac]

I needed to setup home-assistant from scratch, but seems with the latest home-assistant release this docker venv does not work correctly or at least there is weird message in docker logs. Even there is such kind of message below, the configuration is written correctly to the file system. Can this message about matplotlib be ignored?

What I did:

cd $HOME/.docker/home-assistant/docker/
git pull
git log

docker pull homeassistant/raspberrypi3-64-homeassistant:2021.2.1
docker run -d \
  --name=home-assistant --net=host --restart=always \
  -e "TZ=Europe/Vienna" \
  -e "PUID=$(id -u)" \
  -e "PGID=$(id -g)" \
  -e "PACKAGES=iputils" \
  -v $HOME/.docker/home-assistant:/config \
  -v "$HOME/.docker/home-assistant/docker/run:/etc/services.d/home-assistant/run" \
  -v /etc/localtime:/etc/localtime:ro \
  homeassistant/raspberrypi3-64-homeassistant:2021.2.1

The docker log:

Hey @vrabac, thank you for reporting this bug and sorry for not getting back to your earlier. I just merged a commit which adds a proper home directory for the homeassistant user, which – I hope – solves your problem. Could you try with the version from master and report back? Thanks!
