Debian Testing pulled a new Virtualbox version (4.3.2) into my system. Which is apparently incompatible with Vagrant 1.2.2
$ vagrant up Vagrant has detected that you have a version of VirtualBox installed that is not supported. Please install one of the supported versions listed below to use Vagrant: 4.0, 4.1, 4.2
A debian bug is already open, but the package update is only available in sid, not testing.
Thanks lazyfrosch for the hint about pinning unstable and pulling only newer vagrant updates.
# cat </etc/apt/sources.list.d/unstable.list deb [arch=amd64,i386] http://ftp.de.debian.org/debian/ sid main non-free contrib EOF # cat < /etc/apt/preferences.d/pinning Package: * Pin: release a=sid Pin-Priority: -100 Package: * Pin: release a=unstable Pin-Priority: -100 Package: vagrant Pin: release a=unstable Pin-Priority: 991 EOF # apt-get update # apt-get install vagrant
Now it works like a charm again 🙂
