I'm trying to install Virtualbox on Ubuntu 12.10 64bit, (Kernel 3.5.0-23). I've already installed dkms, build-essential, linux-source, linux-kernel-headers, ... . I still get this error:
Error! Your kernel headers for kernel 3.5.0-23-generic cannot be found. Please install the linux-headers-3.5.0-23-generic package, or use the --kernelsourcedir option to tell DKMS where it's located
The kernel headers and source are in their appropriate place:
ls /usr/src linux-headers-3.5.0-23 linux-source-3.5.0 linux-headers-3.5.0-24 linux-source-3.5.0.tar.bz2 linux-headers-3.5.0-24-generic
I know there are tons of similar questions on different forums, I've tried all of them. None of them works. Can anyone help me please?
