I run Lucid 10.04 (because of a specific application I can' t upgrade) and need to use virtualbox. Using synaptic I installed it, but I can't start any appliance because it says that virtualbox-dkms isn't installed. When I try to install it, it complains that the kernel source isn't installed. However, synaptic shows that I'm running kernel 184.108.40.206.36 and the kernel-source (installed using synaptic) shows it is version 3.0.0-32.51. This doesn't match obviously, but I can't get it right so far. Is there any solution to this?
