Another job is running for job group home_assistant_core / fails to start

Installation Home Assistant OS
1

hardware: raspberrypi5-64
operating_system: hassos 17.1
homeassistant 2026.2.2
supervisor 2026.02.1

info keeps giving state: startup (expected running?)
companion app has lost connection
ping correctly returns

Yesterday I had a few updates which seemed to work OK until in the night.
new in trouble shooting here but when I try things like core stop I get another job is running for job group home_assistant_core
I have no idea why this all of the sudden started.

How can I fix this running job error and ultimately get my installation running again? It ran without any problems during nearly 2 months. It would already be OK for me to restore from an automated backup, if that is possible from the CLI.

Entso-e integration? You need to fix it:

bingo!
Thanks for the quick answer. It’s all back online again after I was able to successfully run

core stop
core restart --safe-mode

which gave me back the GUI where I could disable the Entso-e integration and restart HA.
It’s a pity that this integration can cause this problem…

Took some hours to find this topic, but finally HA is up again.

ha> login

(spawns root shell)

# cd /mnt/data/supervisor/homeassistant/custom_components
# mv entsoe entsoe.disabled
# reboot

WOW that was a nasty one! It took me a whole day to fix. Luckily it is a lazy Sunday; I could not have explained this on a random week day. “Why do the lights not work”?

A custom component that can take down Home Assistant. That should be something we want to prevent…

Thanks! Helped a lot.

Core wouldn’t stop at first. So perfomed a reboot, then was able to stop the core and start in safe mode if anybody has the same issue.

how can I get there?
I think I disabled SSH.
I don’t have a mini HDMI cable to connect my RP4 to a monitor.
Putting the sd card into my desktop’s reader still doesn’t allow me to alter files as I’m not the owner then.
-edit-
I opened above mentioned directory in terminal
With the sudo command I could run:

sudo mv entsoe entsoe.disabled

and it worked!

Is there a line command I can put into my browser to start in safe mode? Or how can I do this? I have a HA Green and use a MacBook Air. I don’t know how to use Terminal or any of the command line editors

After everything failed I have now connected a keyboard and a monitor. I can stop the core but when I type in core restart --safe-mode I always get error message another job is running for job group home_assistant_core. I cannot get out of this. Anyone any idea how to solve this issue?

Follow the entsoe post/thread.
Disable the entsoe integration through the cli.
Starting in safemode did not work for me either

Damn this post took me a while to find but saved the day.

THANKS!!!

ok, finally I managed to stop the integration. For me it worked in the safe mode to go into File Editor and manually delete all files and directories of the entsoe integration (/homeassistant/custom_components). Then after reboot it could start the GUI without getting hung up.

Nice going, it worked for me! Many thanks!
