Any solution available so far?
You have 2x choices:
Supported and old Ubuntu
There is no Ubuntu 19 support yet - you must downgrade to Ubuntu 18.x to retain support.
Unsupported and working
This git repository:
Has patches to support the latest VMWare workstation (15.0.4) on Linux 5.0 - you need to select the correct branch and then compile and install the kernel modules.
For me, that looked like this (workstation already setup with kernel headers, compilers, etc):
git checkout workstation-15.0.4
sudo make install
After rebooting it Workstation 15.0.4 works OK. Completely unsupported but better that not working...
You will have to repeat the above if you upgrade VMWare Workstation until Ubuntu 19.x is supported, so make sure a branch exists before upgrading....
