Update Ubuntu Linux and Linux Mint with out Terminal step1: go your Linux operating system menu and open software update step2: check your software update available or not. if available then press enter and put your password . after putting password press enter and the system will start automatically update

Update Ubuntu Linux , Linux Mint with help of Terminal updating system is very good. you have to update our system every  once week . this is very easy you have to follow few steps. Step1: open a terminal (ctrl + alt + t) step2: write on terminal sudo apt-get update and press enter   step3: enter your password and press enter then automatically update your linux operating system if any update available
