2.2.2 Upgrades

Objectives

To keep the system up to date with the latest fixes and security advisories, upgrades should be done regularly. System upgrade is a two steps process: update the list of available software and, if necessary, upgrade the system. Both operation can be achieved with aptitude, with different options.

In order to ensure the system is protected against latest threads, you should upgrade frequently.

Update the package database

Get the latest list of available packages on the repositories:
