I've already installed VirtualBox version 4.1.18_Ubuntu from this source:
deb http://download.virtualbox.org/virtualbox/debian quantal contrib
Apparently the above source was used to install VirtualBox 4.2 which was automatically removed when I installed the vagrant. So, I suppose that the current installed version is from the default Ubuntu source.
When I installed the vagrant (from the default Ubuntu 12.10 source) and tried to run my box with
vagrant up I got this error message:
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
Is there any way to run vagrant with my VirtualBox? Installing newest vagrant version could be also as a solution (the current one: 1.0.3).
sudo apt-get purge virtualbox* virtualbox-4.2 vagrant and
sudo apt-get install vagrant, it didn't help.
