I just followed the answer in: How to install Octave without GUI in Ubuntu 16.04? to install octave in ubuntu 16.04 and apparently it worked fine.
Running octave-cli in terminal apparently works
But when I went to run octave clicking on its icon I got the following error:
The settings file /home/user/.config/octave/qt-settings does not exist and can not be created.
Make sure you have read and write permissions to /home/user/.config/octave
Octave GUI must be closed now.
Can anyone please help me fix this, so I can run octave?
