I ran ""apt-get install virtualbox-3.1"" The pre-install script notified me of ""Running VMs found"" which is fine. However when I switched to another console to manually order the VM's to be saved the VBoxManage binary was missing. This caused me to kill the VBoxHeadless processes ... after which I could re-run the apt- command to install the new version. An option to 'save' all running vm's from the pre-install script would be nice, but I can imagine the difficulties to get this fool-proof. An easier solution might me to add some warning in the pre-remove stage Apt output: Get:1 http://download.virtualbox.org lenny/non-free virtualbox-3.1 3.1.0-55467_Debian_lenny [46.2MB] Fetched 46.2MB in 1min49s (424kB/s) Preconfiguring packages ...
