[Errno 13] Permission denied: '/home/pi/pipresents/pp_logs/pp_log.txt' Why??

[atthedropofahat]

Apologies if this is simple, however I cannot find the same issue elsewhere

python /home/pi/pipresents/pipresents.py Traceback (most recent call last): File "/home/pi/pipresents/pipresents.py", line 892, in pp = PiPresents() File "/home/pi/pipresents/pipresents.py", line 89, in init self.mon.init() File "/home/pi/pipresents/pp_utils.py", line 192, in init Monitor.ofile=open(Monitor.log_path+ os.sep+'pp_logs' + os.sep + 'pp_log.txt','w',bufsize) IOError: [Errno 13] Permission denied: '/home/pi/pipresents/pp_logs/pp_log.txt'

This is on a fresh RPi Buster image all packages needed were installed updated and upgraded. Only thing different to my previous install is a USB RTL-SDR and rtl_433 install

*edit - after re-flashing SD card the same issue is happening with no SDR-RTL or rtl_433

My bash script for install (excludes the directory copy steps which I perform manually)

!/bin/bash

apt-get update apt-get upgrade -y

Bit if a mystery this one.

I can't see anything wrong with what you are doing except for the unnecessary install of python3 and vncserver in the bash script.

The error message indicates that the file /home/pi/pipresents/pp_logs/pp_log.txt or its directory, or maybe the /pipresents directory has been made read only. You can check them in the file explorer (right click).

Your only difference to what I do is that I download the zip file from github and copy manually, and do not use a bash script at all. Others use the wget and I've not had complaints.

One slight oddity in the script sudo apt install real vncserver -y Should there be a space between real and vncserver.

Hi Ken. I made a bash after my first install attempt failed, seemed sensible for making a quicker install process. Same failure both times using the wget.

I had PiPresents working on another RPi previously without issue using wget. Thanks for pointing out the space between real and vnc. I will change this.

It looks like the whole pipresents folder is only read only other than root. Will let you know the outcome.

Hi Ken,

For some reason (not entirely sure why using either script caused this) the owner was root and the permissions were only for root to write. I tried chmod withour success but

sudo chown pi /home/pi/pipresents -R sudo chown pi /home/pi/pp_home -R

did the trick.

did a quick google. shell scripts are run as root for some peculiar reason. Need to use su to fix it -
