Home Assistant not starting anymore

Configuration
1

Hello,

My home assistant supervised was running fine on a raspberry pi 4b.
Yesterday, I noticed that some entities were not available anymore and that the names on the side tab were strange, like they were variable names (eg: dev_tools instead of “Strumenti per sviluppatori” /“Developer Tools”).

The system was still, I was out of town for many days so once I noticed it as I came back I rebooted and now Is unreachable. I thought it was a space issue, since many videos were recorded in the meantime, but I deleted them and nothing changed, here is disk space:

/dev/root          29653M 25192M     3209M  89% /
devtmpfs            1759M     0M     1759M   0% /dev
tmpfs               1920M     0M     1920M   0% /dev/shm
tmpfs               1920M     9M     1911M   1% /run
tmpfs                  5M     1M        5M   1% /run/lock
tmpfs               1920M     0M     1920M   0% /sys/fs/cgroup
/dev/mmcblk0p1       253M    50M      203M  20% /boot
tmpfs                384M     0M      384M   0% /run/user/1000

Logging into the raspberry and checking via ssh the status:

sudo systemctl status hassio-supervisor

I get:

● hassio-supervisor.service - Hass.io supervisor
   Loaded: loaded (/etc/systemd/system/hassio-supervisor.service; enabled; vendor preset: enabled)
   Active: inactive (dead)

giu 10 10:35:28 raspberrypi systemd[1]: Dependency failed for Hass.io supervisor.
giu 10 10:35:28 raspberrypi systemd[1]: hassio-supervisor.service: Job hassio-supervisor.service/start failed with result 'dependency'.

So i tried:

sudo journalctl -fu [email protected]

Which gets me:

giu 10 10:33:57 raspberrypi systemd[488]: [email protected]: Failed to determine user credentials: No such process
giu 10 10:33:57 raspberrypi systemd[488]: [email protected]: Failed at step USER spawning /srv/homeassistant/bin/hass: No such process
giu 10 10:33:57 raspberrypi systemd[1]: Started Home Assistant.
giu 10 10:33:57 raspberrypi systemd[1]: [email protected]: Main process exited, code=exited, status=217/USER
giu 10 10:33:57 raspberrypi systemd[1]: [email protected]: Failed with result 'exit-code'.

So guessing it’s something with the used, I noticed that the system:

sudo nano /etc/systemd/system/[email protected]

Is:

[Unit]
Description=Home Assistant
After=network-online.target

[Service]
Type=simple
User=%i
ExecStart=/srv/homeassistant/bin/hass -c "/home/homeassistant/.homeassistant"

[Install]
WantedBy=multi-user.target

Is that user normal? I expected “homeassistant”, but by trying:

id homeassistant

It does not exist. Can I fix it manually?

2

A service name in the form [email protected] actually means: start the [email protected] withe the homeassistant parameter.

%i will be replaced by the parameter.

Now, if that homeassistant user somehow disappeared, it won’t work, indeed.

3

would it be sufficient to create it?

4

If you use the supervised installation method, you’re supposed to be able to answer that question yourself.
We don’t know (nor do we want to know, to be clear) that system.

5

I may have been wrong using that installation method in the first place, I recognize it, but I’ll still wait in case somebody else can be so kind to give me support even if I’m not a real super user

Thanks

I ended up reinstalling home assistant from scratch, loading the back up again. Now it works
