Can't update virtual box

[Jim Byrnes]

I received an update notice for my 12.04 system today.  It included 5 
updates.  Four of them went fine but VirtualBox would not update, kept 
telling me to check internet connection. It is fine.

Here is the error message:

Failed to fetch 
http://download.virtualbox.org/virtualbox/debian/pool/contrib/v/virtualbox-4.3/virtualbox-4.3_4.3.10-92957~Ubuntu~precise_amd64.deb 
404  Not found

Is anyone else having this problem?

Thanks,  Jim
