Installing VMware Tools in an Ubuntu virtual machine

https://kb.vmware.com/s/article/1022525

To install VMware Tools, you must mount the VMware Tools CD image, extract the contents (VMware Tools), and then run the installer.

Note: If VMware Tools is already installed, use these steps to uninstall and then reinstall VMware Tools. When there is product updates, the VMware Tools package is also updated, so an update of the installed version of VMware Tools is required.
