I’ve been struggling to install Zulu Java 11 and I’ve searched everywhere and cannot find a solution. I assumed it would be simple 
I have a manual install of openhab 3 on a raspberry pi 4.
I was hoping I could just apt-get install zulu-11 …
Anyway I tried to find the package and install manually but that did not work. If anyone knows of a solution or can point me to one that would be great thanks.
#go to folder
/usr/lib/jvm
#download
wget -c https://cdn.azul.com/zulu-embedded/bin/zulu11.43.100-ca-jdk11.0.9.1-linux_aarch64.tar.gz
#unpack
sudo tar -xzvf zulu11.43.100-ca-jdk11.0.9.1-linux_aarch64.tar.gz
#create alternative
sudo update-alternatives --install /usr/bin/java java /usr/lib/jvm/zulu11.43.100-ca-jdk11.0.9.1-linux_aarch64/bin/java 100
#update to new alternative
sudo update-alternatives --config java
#check version
java -version
I just get an error and nothing works
-bash: /usr/bin/java: cannot execute binary file: Exec format error
