ubuntu just had a rescent kernel upgrade. You might have remembered installed the kernel header on the older kernel but not the latest. Run this command and re-run parallels-config.
Code:
sudo apt-get install build-essential linux-headers-`uname -r`
PS. if you install the 2.6.20 kernel, either you have to hack the script or wait for Parallels to update the applications. It's the users' responsibility to know exactly what they are updating and what the consequences are. Research before you upgrade and always have a back door. You can still boot on older kernels through grub or lilo to get Parallels working again.
