apt-cache policy virtualbox virtualbox: Zainstalowana: (brak) Kandydująca: (brak)
Virtualbox is not suitable for Debian stable releases because of the lack of cooperation of Oracle on security support (that’s the Debian security team decision).
Since it is not suitable for stable releases, it cannot be included in the testing suite (that’s the Debian release team decision).
It also cannot be included in official backports, as packages must be in testing before they get backported (that’s the Debian backports team’s decision).
