Install VMware : Could not open /dev/vmmon: No such file or directory. Please make sure that the kernel module `vmmon' is loaded
I downloaded the VMware S/W from official website and installed the same. When I try to run any virtual machine it shows error
Could not open /dev/vmmon: No such file or directory. Please make sure that the kernel module `vmmon' is loaded
and says failed to initialize.
I tried this solution and at the last command got the following error
$ sudo mokutil --import MOK.der
EFI variables are not supported on this system``
Also I couldn't install the virtualbox as well, the error was
Kernel driver not installed (rc=-1908)
Answer
There is a lot of posts about the missing vmmon, but this one always bites me after I update ubuntu kernel, and then I forget every time :)

You need to have the very latest version of workstation/player/viewer if you upgrade your kernel Workstation builds modules, and often the build process breaks if there are kernel changes. So if you are having problems first make sure you have the latest version of workstation https://www.vmware.com/products/workstation-pro/workstation-pro-evaluation.html
