apt full-upgrade desempenha a mesma função que
apt-get dist-upgrade .
full-upgrade (apt-get(8)) full-upgrade performs the function of upgrade but will remove currently installed packages if this is needed to upgrade the system as a whole.
dist-upgrade dist-upgrade in addition to performing the function of upgrade, also intelligently handles changing dependencies with new versions of packages; apt-get has a "smart" conflict resolution system, and it will attempt to upgrade the most important packages at the expense of less important ones if necessary. The dist-upgrade command may therefore remove some packages. The /etc/apt/sources.list file contains a list of locations from which to retrieve desired package files. See also apt_preferences(5) for a mechanism for overriding the general settings for individual packages.
