When I installed Kubuntu 20.04 on my machine, Workstation 14.1.7 would not install properly. It complained that vmmon and vmnet were not present. These ordinarily are generated when Workstation is installed, but VMware seems to lag behind in creating appropriate update modules. After a lot of research, I found the following solution, which worked flawlessly (which is more than I can say for me), so I wanted to share it.
The following sequence of commands works for Version 14.1.7:
*********************************************************************************************************
VMWARE_VERSION=workstation-14.1.7
TMP_FOLDER=/tmp/patch-vmware
rm -fdr $TMP_FOLDER
mkdir -p $TMP_FOLDER
cd $TMP_FOLDER
git clone https://github.com/mkubecek/vmware-host-modules.git
cd $TMP_FOLDER/vmware-host-modules
git checkout $VMWARE_VERSION
git fetch
make
sudo make install
sudo rm /usr/lib/vmware/lib/libz.so.1/libz.so.1
sudo ln -s /lib/x86_64-linux-gnu/libz.so.1 /usr/lib/vmware/lib/libz.so.1/libz.so.1
sudo /etc/init.d/vmware restart
*****************************************************************************************************
I found this solution at https://superuser.com/questions/1328401/vmware-workstation-vmmon-broken-on-ubuntu-18-04/1330890
I do not know who devised it. As long as you set the first line to the version of Workstation that you are actually using, you're in business.
