Cannot write to preference file "matlab.prf"

I installed MATLAB on ubuntu in some othe folder than the root folder, and successfully installed it with "sudo apt install matlab-support".

However on opening i receive a long list of errors stating a lot of MATLAB shortcut files could not write to "matlab.prf".

Thank you in advance for the solutions.

Does that directory exist? Are you the owner? Does the directory have x permission for your account? Does the file exist? Are you the owner? Do you have w permission for your account for it?

Yes , I am the owner and the directory exists ,

Executed this command on the terminal

sudo chown -R $USER /home/$USER/.matlab/R2018b/

Should be R2019a for your purposes
