when I type in uname -r it returns "2.6.32-22-generic" but I'm running on 2.6.32-23-generic. This is keeping me from compiling the vbox driver because is says "cannot find header files for 2.6.32-22-generic." 2.6.32-23-generic is the only kernel installed. I don't know what to do. Please tell me any other commands output i can post to help.
