TP-Link Omada Controller - Cannot find any VM in Java Home /usr/lib/jvm/default-java

I have small problem. Today I'm trying to setup Omada Controller (same as UniFi Controller) on my RaspBerry Pi 3. Everything looks good, but when I'm trying to start the controller, it shows this error - "Cannot find any VM in Java Home /usr/lib/jvm/default-java." I'm trying to fix it, but without success. I have installed all versions of java, but it doesn't help. Any options, how to fixit easily? In the description below is a screenshot, wiht error. Thanks for any help. k

Here is an updated guide for the latest version 3.2.1

More or less you need to check your Java install and make sure the symbolic link to the Java home is correct:

apt-get install jsvc
apt-get install openjdk-8-jdk
sudo update-alternatives --config java
cd /usr/lib/jvm
ln -s java-8-openjdk-armhf default-java
tpeap start

If you still have issues then follow each step again from the guide.
