Package: apt Version: 0.9.12 Quoting apt-get's manpage:
,---- | upgrade | upgrade is used to install the newest versions of all packages | currently installed on the system from the sources enumerated | in /etc/apt/sources.list. Packages currently installed with | new versions available are retrieved and upgraded; under no | circumstances are currently installed packages removed, or | packages not already installed retrieved and installed. `---- This paragraph has been unchanged for the last 14 years, but the last half-sentence is no longer correct. In apt 0.9.12 apt-get learned an option which does allow installing new packages, as mentioned further down in the manpage. ,---- | --with-new-pkgs | Allow installing new packages when used in conjunction with | upgrade. This is useful if the update of a installed package | requires new dependencies to be installed. Instead of holding | the package back upgrade will upgrade the package and install | the new dependencies. Note that upgrade with this option will | never remove packages, only allow adding new ones. | Configuration Item: APT::Get::Upgrade-Allow-New. `----
