virtual box .deb file conflicts with installed one

[oxy]

Hi all,

System: Ubu 12.04 on unity

it seems that virtualbox is not found of solving these little
conflicts. But i also do not want to risk force install in those conditions.
When trying to upgrade my vbox to the new released version i get the following:

# dpkg -i virtualbox-4.2_4.2.6-82870~Ubuntu~precise_amd64.deb
Selecting previously unselected package virtualbox-4.2.
dpkg: regarding virtualbox-4.2_4.2.6-82870~Ubuntu~precise_amd64.deb
containing virtualbox-4.2:
 virtualbox-4.2 conflicts with virtualbox
  virtualbox-4.1 provides virtualbox and is present and installed.
dpkg: error processing
virtualbox-4.2_4.2.6-82870~Ubuntu~precise_amd64.deb (--install):
 conflicting packages - not installing virtualbox-4.2
Errors were encountered while processing:
 virtualbox-4.2_4.2.6-82870~Ubuntu~precise_amd64.deb


Any idea?...
thx...
