I've installed Ubuntu 16 LTS 64 bits in a secure boot UEFI enabled machine.
Ubuntu works well but when I installed Vmware Workstation 12 in that machine it doesn't work.
It doesn't load vmmon module.
Trying loading using insmod it says it cannot found keys.
Searching in internet i've found that vmmware modules are not signed and when it tries to load that modules, kernel refuses to load because they are not signed.
I've disabled secure boot in the UEFI setup and now Vmware is working ok , modules are loading without problems.
When will vmware sign modules for using in a secure BOOT UEFI enabled machine?
Are there another way for making vmware modues loading in a secure boot UEFI machine without signing manually and resigning each time kernel is updated?
Also here is the publish KB about Workstation:
Oh my days... I have spent an entire day looking for this solution. Thank you so much, it was secure boot all along!
