After upgrading to Ubuntu 11.04 from 10.10, you might encounter errors while using Virtual Box. Trying to compile Virtual Box throws the following error: Error! Your kernel headers for kernel 2.6.38-10-generic-pae cannot be found at /lib/modules/2.6.38-10-generic-pae/build or /lib/modules/2.6.38-10-generic-pae/source.
