Error running Octave in Ubuntu 16.04

I just followed the answer in: https://unix.stackexchange.com/questions/280195/how-to-install-octave-without-gui-in-ubuntu-16-04#new-answer?newreg=a3e30a76cc184b50ae80b8c39bf2463d 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?
