Autostart problem on virtualenv raspberry pi

Aaraeus · April 25, 2017, 5:25pm

HI all,

So I had an issue where I couldn’t edit configuration.yaml from SSH. I therefore created a new group called hass and added my users pi and homeassistant.

However when I restarted homeassistant using the following…

sudo systemctl restart home-assistant@ultron

… I’m getting the following error on startup.

● [email protected] - Home Assistant
Loaded: loaded (/lib/systemd/system/[email protected]; enabled)
Active: failed (Result: exit-code) since Tue 2017-04-25 18:17:24 +01; 6s ago
Process: 21897 ExecStart=/srv/homeassistant/homeassistant_venv/bin/hass -c /home/homeassistant/.homeassistant (code=exited, status=203/EXEC)
Main PID: 21897 (code=exited, status=203/EXEC)

I’m actually really baffled here. Any ideas guys? I’m at my wit’s end and quite close to just wiping and starting again, this time using AIO installer since it seems to work for others so well.

Bit more info - the last thing I wanted to edit was adding an nmap process to scan my network every 10 minutes for known devices.

Weirdly my HA web service still works (???) but my iOS devices no longer show up. Config file is OK, and the error log from the developer info page isn’t updating at all.

I assume that the HA user has no longer write access to your config files.
It can read configuration.yaml, so web service works. But for ios an logfile it needs write access.
What if you login as HA user, can you write the files?

Aaraeus · April 25, 2017, 6:21pm

I just logged into the HA user and opened the file ‘ios.conf’, and tried to save it with ‘:w’. The file is readonly… I assume this means you’re right!

A red bar comes up at the bottom saying:

E45: ‘readonly’ option is set (add ! to override)

But when I try to override, it says:

"ios.conf E212: Can’t open file for writing

How do I fix this? Is there a solution here that still allows me to continue to configure my files outside of the terminal? Kinda hate using vi so I’m ssh’ing to the files and using atom on linux.

VDRainer · April 25, 2017, 6:27pm

Please login as pi and post the output of:
sudo ls -la /home/homeassistant
and
sudo ls -la /home/homeassistant/.homeassistant

Use nano, simply the best.

edit: sorry, forgot to mention, the ‘pi’ username is actually ‘kintesh’ on here.

edit2: … and “hass” is the group I’ve added both “kintesh” and “homeassistant” to.

VDRainer · April 25, 2017, 6:43pm

Try:
chown -R homeassistant:hass /home/homeassistant/.homeassistant
then all files are owned by homeassistant.
then try:
chmod -R ug+rw /home/homeassistant/.homeassistant
so users in group hass can edit them to.

Aaraeus · April 25, 2017, 6:52pm

First one didn’t work, then I realised I needed to run it as a sudo user.

I just restarted HA though and it still won’t work. I checked ls-la on…

Also just double checked and I now have write access to ios.config under homeassistant, so that bit has worked.

Hmm, let me shutdown and restart my pi.

Edit: Yeah, still not working.

On the bright side, my error log is up and running so it looks like homeassistant has write access again for sure!

Hmm, I’m not sure whether posting my ip like this is an issue, but I guess all the forums and websites I’m registered at already have it.

The following errors have been logged this session:

Don’t know what all those errors mean. Maybe you switch all permissions back to the beginning. User an group should be homeassistant, so try:
sudo chown -R homeassistant:homeassistant /home/homeassistant

Aaraeus · April 25, 2017, 7:18pm

Hmm, that didn’t work.

I have a feeling I’ve messed up somewhere with:

my iOS config file (no idea how to refresh it)
I can’t get nmap to scan correctly (it should be scanning every x seconds or something for new devices)

if I can get both of those to work I think most of these errors will disappear and it might mean a clean restart.

Worth a shot, I’ll keep digging.

Thank you very much for your help!

VDRainer · April 25, 2017, 7:20pm

Just rename the ios.conf to ios.conf.bak and give it a try.
I think it get’s created when you login from your iphone.

Aaraeus · April 25, 2017, 7:28pm

No such luck I’m afraid.

I think I might just reflash and install using AIO installer.

Something must have gone wrong while trying all this out. I’d like to at least mod my pi’s name - hopefully AIO installer allows that!
