I was following the instruction to install a Brother printer MFC-L6510DW on my Linux Lite, but when I get to the 2nd step that is go to "super user" (su) or (sudo su) I get the message Authentication Failure when I put the password, and I only have one password for that OS. What am I missing or do wrong? why do I get that message? I can't complete the installation because of that. Would somebody help me?
