Hi, I recently installed Matlab on Linux using the official installation software from Matlab and running it as sudo.
Now I can open it from the terminal (matlab &) but I’m having trouble installing the Signal Processing Toolbox. First it threw a permission error because I was running it as my normal user but it wanted to write to /usr/local/Matlab/R2021b, so I had to change the permissions of that folder temporally (I couldn’t just run matlab as superuser because the license wouldn’t work).
Now I tried installing it, but it fails because “something unexpected ocurred”. The messages I got on the terminal are these:
Gtk-Message: 12:02:29.916: Failed to load module "canberra-gtk-module"
