[SOLVED] JDK is installed on mac but i'm getting "The operation couldn’t be completed. Unable to locate a Java Runtime that supports apt." sudo apt update

Issue

I'm trying to run the command sudo apt update on my terminal in MacOS

I'm getting this message in response: The operation couldn’t be completed. Unable to locate a Java Runtime that supports apt. Please visit http://www.java.com for information on installing Java.

I saw a similar question here, however even though I made sure to install the JDK like the solution suggested I'm still getting the same response.

I also tried pasting

export PATH="$HOME/.jenv/bin:$PATH"
eval "$(jenv init -)"
export JAVA_HOME="$HOME/.jenv/versions/`jenv version-name`"

Into my .zshrc.save folder and had no luck.

When I run java -version in the terminal this is what I get back:

java version "15.0.2" 2021-01-19
Java(TM) SE Runtime Environment (build 15.0.2+7-27)
Java HotSpot(TM) 64-Bit Server VM (build 15.0.2+7-27, mixed mode, sharing)

Solution

20 years ago, java shipped with a tool called apt: Annotation Processor Tool. This tool was obsolete not much later.

What that update-node-js-version is talking about, is a completely and totally unrelated tool: It's the Advanced Package Tool, which is a tool to manage installations on debian and ubuntu - linux distros. You do not want to run this on a mac, and the instructions you found are therefore completely useless: That is how to update node-js on linux. Your machine isn't linux.

Search around for answers involving brew, which is the go-to equivalent of apt on mac. And completely forget about java - this has NOTHING to do with java - that was just a pure coincidence.
