Comment 3 for bug 133020

Yes, I've seen this as well in the Gutsy final release I just upgraded to last night. vmware-server 1.0.3 will not run in Gutsy because of the kernel modules mismatch.

Workaround:
1. Back up your license file found in: /etc/vmware/license.vs.1.0-00 or at least save the serial contained in that file somewhere.
2. Uninstall vmware-server 1.0.3 including purging all configuration.
3. Make sure you have the package build-essential
4. Download vmware-server 1.0.4 directly from http://vmware.com/download/server/
5. Unpack and run vmware-install.pl, usually it is fine to accept all defaults, and enter the license key from step 1.

and you should be back up and running.
