Be sure to add your new user to the sudoers file. Once you have done this your new user can use the sudo command to perform super user functions.

1. Type su to assume the root user
2. Type visudo to open the sudoers file (don’t edit the file with nano or vim)
3. Add your user name below the root user user ALL=(ALL:ALL) ALL
4. Log out of the root user by typing exit

• Type sudo apt-get update or whatever you need.
