apt-get

• Synchronize list of packages and versions available. This should be run first, before running subsequent apt-get commands:

apt-get update

• Install a new package:

apt-get install {{package}}

• Remove a package:

apt-get remove {{package}}

• Upgrade installed packages to newest available versions:

apt-get upgrade

• Upgrade installed packages (like "upgrade"), but remove obsolete packages and install additional packages to meet new dependencies:

apt-get dist-upgrade
