I'm trying to install the Guest Additions in VirtualBox 4.04. Host OS is Ubuntu desktop 11.04 64bit, guest OS is Ubuntu server 11.10 64bit. $ sudo ./VBoxLinuxAdditions.run After some output this line is printed: The headers for the current running kernel were not found. But the headers are installed, at least accordingly to dpkg: $ dpkg --get-selections | grep linux-headers linux-headers-3.0.0-12
![Error: kernel headers not found. (But they are in place)](https://cdn-ak-scissors.b.st-hatena.com/image/square/664a2d3dc991972667a15e0e849615b9670c436b/height=288;version=1;width=512/https%3A%2F%2Fcdn.sstatic.net%2FSites%2Faskubuntu%2FImg%2Fapple-touch-icon%402.png%3Fv%3Dc492c9229955)
