You’ll need to use the apt-get command to install and update the Ubuntu environment’s software. Be sure to prefix these commands with “sudo”, which makes them run as root–the Linux equivalent of Administrator. Here are the apt-get commands you’ll need to know:
•Download Updated Information About Available Packages: sudo apt-get update
•Install an Application Package: sudo apt-get install packagename (Replace “packagename” with the package’s name.)
•Uninstall an Application Package: sudo apt-get remove packagename (Replace “packagename” with the package’s name.)
•Search for Available Packages: sudo apt-cache search word (Replace “word” with a word you want to search package names and descriptions for.)
•Download and Install the Latest Versions of Your Installed Packages: sudo apt-get upgrade
