apt-get install {{package}}

• Remove a package:

apt-get remove {{package}}

• Remove a package and its configuration files:

apt-get purge {{package}}

• Upgrade all installed packages to their newest available versions:

apt-get upgrade

• Clean the local repository - removing package files (.deb) from interrupted downloads that can no longer be downloaded:

apt-get autoclean

• Remove all packages that are no longer needed:

apt-get autoremove
