Script not running in a new notebook

Troubleshooting
1

Hello guys, I didn’t have the time to setup my new BrewPi spark 3 and still using my old Arduino Uno Rev C.
The notebook in which I was running the web interface stops working and I installed a new one with Debian “Jessie”, the old one was running Debian “Wheezy” with no problems using the Legacy branch and Arduino code v0.2.10.

After setting up the new notebook, I wasn’t able to start the script and I’m having several errors:

brewpi@brewpi:~$ sudo -u brewpi python /home/brewpi/brewpi.py

And in Device Configuration --> Device List web interface:
Error while receiving device configuration: SyntaxError: Unexpected token C in JSON at position 0

I reinstalled the notebook twice with no luck, at this point seems that Jessie doesn’t work with BrewPi, but on the other hand, I could run it when I tested my new BrewPi Spark 3 in a VM in my MAC, so I’m a bit confused what is going wrong here.

Thanks in advance.

I think I found the root cause of this.
I installed it using the automated script, and seems that not all the permissions are properly granted.
The dialout permission is not granted thru the automated script, I realized it when in a try, I followed the manual installation procedure in which the permissions are mentioned.
The solution was as simple as “sudo usermod -a -G dialout user” command.
Also upgraded Debian 9 (stretch) latest stable release and works with no issues.
Regards,
Nor.
