I can confirm your results with Snap version of Ubuntu make, so let's remove it

sudo snap remove ubuntu-make

And then install version from repository

sudo apt-get install ubuntu-make

Then install NetBeans IDE with umake command:

umake ide netbeans

Then log-out or reboot.
You can find NetBeans in Applications->Programming->Netbeans IDE or run it with netbeans command.
