I am using xubuntu in virtual box and I ran the sudo update-alternatives --config java command and it says "There is only one alternative in link group java" and next if i run the sudo gedit command....it says that sudo gedit command not found...what should I do?

Yoo thank you soo much. I've been trying to fix java for the past two hours, and all I had to do is watch this video?!?!

Excellent video

When I do $ sudo update-alternatives --install /usr/bin/java java /usr/lib/jvm/jdk-14.0.2/bin/java 1 (with the correct version) it does nothing, and just continues to the next line. It doesn't say anything like yours

so I'm having troubles... whenever I do "sudo update-alternatives --install /usr/bin/java java /usr/lib/jvm/jdk-16/bin/java 1" it says "update-alternatives: error: alternative path /usr/lib/jvm/jdk-16/bin/java doesn't exist". Please help!
much appreciated! :)

Thanks, helped me install for minecraft 1.17

Thanks I didn't know that environment file

Good work bruhhh!!!
