Updates the list of available packages from the apt sources
(this is equivalent to “apt-get update”)
Upgrades installed packages to their most recent version.
Installed packages will not be removed unless they are unused (see the
Automatically Installed Packages” in the aptitude reference
manual). Packages which are not currently installed may be installed
to resolve dependencies
unless the --no-new-installs command-line option is supplied.
It is sometimes necessary to remove one package in order to
upgrade another; this command is not able to upgrade packages in such
situations. Use the
full-upgrade command to upgrade as many packages as possible.
Upgrades installed packages to their most recent version,
removing or installing packages as necessary. This command is less
safe-upgrade and thus more likely to perform unwanted
actions. However, it is capable of upgrading packages that
safe-upgrade cannot upgrade.
This command was originally named dist-upgrade for
historical reasons, and aptitude still recognizes dist-upgrade as a
synonym for full-upgrade.
