Processing 3.3.6 - Could not save the Preference File

edited January 15 in Raspberry PI

Hello, i want to run on my raspberry 3 with raspbian processing 3.3.6. After the flawless installation (curl hhtps://processing.org/download/install-arm.sh | sudo sh), i get the start of processing (whether by start over terminal or menu) following error: "Could not save the Preference File".

What is the problem there. Thanks

  • @merida That's odd? You're using a stock (full) Raspbian distribution? Are you running as the default "pi" user?

    What's the output when you do ls -l ~/.processing/preferences.txt? (Also try with ~/.processing and ~.)

    If I switch to root with "sudo su", the error message does not come anymore.

    But does not that quite right "rw" does not mean that other users (even pi) have write permissions?

    pi@raspberrypi:~ $ ls -l ~/.processing/preferences.txt
    -rw-rw-rw- 1 root root 3087 Jan 10 15:00 /home/pi/.processing/preferences.txt)
    

    What should I change to start "processing" under pi correctly?

  • You must have executed Processing as root the the firs time it was run. This created a preferences.txt, which your normal user can't modify any longer.

    Delete your preferences by executing sudo rm -Rf /home/pi/.processing.
