Could you help me to reset my root password?
After upgrade from Ubuntu 14.04 to 16.04 I lost my previous ability to delete my files. Now my laptop is full and I can not remove anything and install updates or whatever.
I am set as administrator and with dmin rights, but when I go to any file and try to deley shows me im not the owner ad have no premission. The shown user is like 1001 who is also me. Dont have connection with the person who made the first laptop installation and who probably set himselves as root. I even remember any pass , but dont see any option to enter it as root for that user, because it doesnt appears on the screen.
If you have any suggestions how could I deal with the situation, please, let me know.
