Situation:
I have a python script on my raspberry pi. If I execute it manually there is no problem, it works exactly as it's supposed to.
When I create a cron job with :
sudo crontab -e
the script is "executed", because it appears in /var/log/syslog at the correct time. Other cron jobs are executed correctly.
My entry:
0 18 * * * /usr/bin/python /home/user/script.py
In the log it's correct: every day at 18:00:00. But nothing happens. I have no idea why the script isn't executed correctly.
It's maybe a stupid mistake, but I am not soooo skilled in linux.
