I was using Ubuntu 14.10 on my setup and I had Virtualbox running fine.
Then my OCZ Vertex 2 (SSD) died unexpectedly and I had to reinstall everything.
But, because the Intel Graphics Drivers weren't installing on Ubuntu 14.10 (February 2015), I chose to install Ubuntu 14.04 LTS. What a surprise that the new April 2015 drivers will ONLY install on Ubuntu 14.10! So I then upgraded to Ubuntu 14.10 and, after installing the drivers I updated to 15.04.
Why I did this introduction? Because maybe something wrong happened during the update, especially with the kernel update.
When I install Virtualbox I get this error:
Trying to register the VirtualBox kernel modules using DKMS. Error! Your kernel headers for kernel 3.19.7-031907-generic cannot be found. Please install the linux-headers-3.19.7-031907-generic package, or use the --kernelsourcedir option to tell DKMS where it's located ...failed! (Failed, trying without DKMS) Recompiling VirtualBox kernel modules ...failed!
Before, the kernel was like 3.16, I manually updated to 3.19.7, but it can't find kernel headers: what can I do?
