WARNING: environment variable DISPLAY is not set (netbeans)
I was trying to install Netbeans in Xubuntu. I had installed Netbeans using Snapd.
sudo snap install netbeans --classic
I was trying to start Netbeans then I got an error which was looking like this
can't find JDK (I completely don't remember the error but I had fixed it)
I had solved it this way
$which javac /usr/bin/javac
Then when I try to start netbeans again I get the error.
netbeans /snap/netbeans/50/netbeans/platform/lib/nbexec: WARNING: environment variable DISPLAY is not set
I had quick search in DuckDuckGo. I didn't search in Google for "safety". I couldn't find any related problem in DuckDuckGo.
Note : I was using Java in Android Studio. But I couldn't find java in my system that's why I had to install it again.
sudo apt-get install openjdk-16-jdk-headless
I had installed default-jdk, jre and java although I didn't get any GUI of netbeans. I was thinking what was missing. While visiting lots of site I had seen oracle (Article) then I remembered I didn't install Oracle after installing Oracle I can access GUI of netbeans.
sudo apt-get install oracle-java16-installer
