HA Stopped working

hareeshmu · September 15, 2016, 5:06pm

My Home Assistant (homeassistant 0.28.0) stopped working all of a sudden.

Here is the log. I have tried updating to homeassistant-0.28.2, but no luck in starting HA.

Please help.

You have a corrupt pyc file, which is a compiled python file. This happens sometimes. It is often hard to pinpoint the culprit pyc file, so I find it easier to delete all pyc files as they will be re-created the next time a specific python file is accessed, however, in your case, it may just be the homeassistant and pytz packages as shown in your error log.

From the terminal of your hass system, cd to the python site-packages folder for homeassistant:

cd /srv/hass/lib/python3.4/site-packages/homeassistant

Then type this and hit return:

sudo find . -name “*.pyc” -type f -delete

Then cd to the pytz site-packages folder:

cd /srv/hass/lib/python3.4/site-packages/pytz/

And repeat the command:

sudo find . -name “*.pyc” -type f -delete

After deleting the pyc files from both folders, try restarting Home Assistant.

If you still get similar errors, then try deleting ALL pyc files from ALL packages:

cd /srv/hass/lib/python3.4/site-packages

sudo find . -name “*.pyc” -type f -delete

Don’t worry, you can’t damage the system by remove the pyc files.

Awesome @jbardi, That was too quick and saved my day and HA.

I had to switch off my lights which was turned on by automation and there was no manual override.
I was thinking what I will do now to turn off the lights.

Thank you so much for your timely help, much appreciated!

Glad it worked out for you

hareeshmu · September 15, 2016, 5:33pm

This worked out for me, just added “sudo” for the find and delete

cd /srv/hass/lib/python3.4/site-packages/homeassistant

sudo find . -name "*.pyc" -type f -delete

Thanks once again @jbardi

jbardi · September 15, 2016, 5:34pm

I also got the same error today tried everything still nothing… Can’t even downgrade or upgrade. Tried removing all .pyc files but still nothing . This is the third time i got this problem and first 2 times deleting files worked. Can anyone guide as i don’t want to start from scratch again.

Note for docker user: Sometimes the files seems to get corrupted inside the docker images. If this happens you can remove the image.

docker rmi <<hass-image-name>>

Start it again like you’re used to. The image will downloaded again
