Package: virtualbox Version: 4.3.18-dfsg-3+deb8u3 Hi,
virtualbox 4.3.18-dfsg-3+deb8u3 has the following in Depends: python (>= 2.7), python (<< 2.8), python2.7 . But this means that when installing virtualbox:amd64, the package management will also want python:amd64. I think Depends should actually have the following: python:any (>= 2.7.5-5~), python:any (<< 2.8), python2.7:any . That way, it's possible to install VirtualBox on a 64-bit machine with 64-bit kernel and 32-bit Python interpreter. The reason for installing the 64-bit version of VirtualBox is because the installed virtualbox package apparently has to match the kernel architecture. The 32-bit version will install, but starting an actual VM won't work on a 64-bit kernel. The reason for sticking with the 32-bit version of Python is because there are other broken packages that don't have the :any in Depends, and as a result, switching to a 64-bit Python interpreter would require also switching over a whole bunch of other packages. The reason for bumping the dependency from 2.7 to 2.7.5-5 is that 2.7.5-5 is the first package version that had "Multi-Arch: allowed". The package version in jessie is 2.7.9-1, so I think a dep on >=2.7.5-5 is OK. When I force installation of virtualbox:amd64 with python:i386, VirtualBox seems to work well. -- Adam
