Home assistant 404 error

Troubleshooting
1

Hi,

I tried to install Home assistant, the install seems to have worked and HA is running, but if I go to the web UI I get a 404: not found error.

I’m running DietPi v6.32.2 on a RPi 2 Model B.

I looked at the forum, and there was an old thread about this issue from 2019, but I can’t find a resolution.

I’m not a total novice user, but am by no mean an expert either!

Any ideas?

Thanks
Paul

Hi,

many thanks for your message, what URL you are using to access HA?

3

sudo apt-get install libjpeg-dev zlib1g-dev

Restart HA and after a few minutes it came up…

thx for sharing your solution. For me it was enough to perform apt install libjpeg-dev because zlib1g-dev was already present/installed.

Looks like some new dependency that would need to be added to dietpi-software installation process.

EDIT1:
just verified the apt dependency that will be installed by dietpi-software together with HA from

DEPS_LIST="gcc libc6-dev make zlib1g-dev libbz2-dev libreadline-dev libssl-dev libsqlite3-dev libffi-dev $custom_apt_deps"

zlib1g-dev is already there, I will open PR on Github to add libjpeg-dev as well.

EDIT2:
PR up https://github.com/MichaIng/DietPi/pull/3781/files

Resolved for DietPi v6.33, many thanks!

Hello, I have a similar problem with Home-Assistant on Dietpi. It is running, yet no web interface is available. Netstat tells me nothing is listening on port 8123, which I believe is the port on which it should be listening. I see home assistant running in htop.
I have installed using the dietpi installer, however, the logs in /mnt/dietpi_userdata contain many errors about missing dependencies, for instance:

Have I missed something? How can I resolve from this?

Please run: systemctl restart home-assistant
It is a known issue that the service fails to install all dependencies on first run, not sure why. See the “IMPORTANT” note on our docs: https://dietpi.com/forum/t/dietpi-software-details-for-all-installation-options/22/113

That’s the thing, I tried that. But it won’t work. This is what I get:

systemctl restart home-assistant
Failed to connect to bus: No such file or directory

9

systemctl needs to be run with root permissions: sudo systemctl restart home-assistant
Shame on systemd to throw such a misleading error message :frowning:.

Hi,

For the life of me I cant remember or find the default homeassistant web login detauls. Any ideas anyone?

Managed to reinstall it and got it to show up the web UI.

Thanks
Paul

I’m running a test install to assure, but on first access you simply choose your admin username and password, not?
EDIT: Yes in first web access you choose credentials freely, so no default login.
