Hi,
I am not experienced with python, but deemed it safe to just follow the pet_companion instructions to create a new app by first creating a folder.
Since the folder name was not listed in the app/example list, as was described in the example, I rebooted the camera through the web interface and could not get the web interface back up. Connected through ssh, deleted the folder and looked for hidden files, as I read in other posts, but nothing worked.
how can I get the camera web browser back up?
Hello,
Sorry for the problems!
To give me an idea of what could be going wrong, can you please run the command below through SSH or via keyboard/monitor and tell me what the output is?
sudo journalctl -f --unit vizy-server
Edward
thanks for the quick reply and sorry for the delay in getting back.

The likely cause is [quote=“goetz, post:3, topic:121”]
'/home/pi/vizy/apps/. .DS_Store’
[/quote]
Try connecting again via SSH and deleting it.
unfortunately it did not change the behaviour
content looks like this now:
pi@vizy : ~/vizy/apps $ ls -a
. … birdfeeder motionscope
pi@vizy : ~/vizy/apps $ cd …
pi@vizy : ~/vizy $ ls -a
. … apps ._.DS_Store .DS_Store etc examples scripts sys
pi@vizy : ~/vizy $
should I delete the “DS_Store” in parallel to the “apps” folder as well?
sorry - had a similar error message on “examples” , deleted both “DS_Store” files and now have access to the browser interface again.

Those DS_Store files are created and used on the Mac. Linux doesn’t use them, but they can cause the Vizy software to fail - as you’ve seen. You can safely delete them on the Vizy and if you get them all, your problem should resolve.
You should avoid copying whole folders from the Mac to the Vizy as it will sometimes include DS_Store files and if they end up in the wrong place the problem will re-occur.
Also if you connect to the Vizy from your Mac using Samba (SMB) it can create DS_Store files on the Vizy too.
If you are using SMB, there’s an article here that talks about how to disable the DS_Store file creation from the Mac side: https://support.apple.com/en-us/HT208209
Hope this helps.
Thanks for the good information Ed 
This issue was fixed in 0.1.100 – that is, as far as we can tell. Can someone verify that the extra files no longer cause issues?
thanks
Edward
Yes, I copied a couple of those files to an app directory and the issue didn’t happen.
Sorry, I didn’t know it’d been fixed or I’d have suggested updating!
Ah, nice – thanks for giving it a try
