After Upgrading my Ubuntu the other day to Ubuntu 11.04 (Natty Narwhal), My VMware Workstation 7.1.3 that was working perfectly before the upgrade stopped working and kept throwing the following error when trying to compile its modules with the new Kernel: “Unable To Build Kernel Module see log file /tmp/vmware-root/setup-7357.log for details.” Below is a screen shot of the lovely error message:

Ubuntu 11.04 VMware Workstation 7.1.3 error

I have followed the error instruction and checked the log file setup-7357.log pointed out by the error message shown above  to find the following messages:
