Installing from the APT repository

I have been unable to install ES 7.8 per the instructions here


  1. wget -qO - | sudo apt-key add -
  2. sudo apt-get install apt-transport-https
  3. echo "deb stable main" | sudo tee -a /etc/apt/sources.list.d/elastic-7.8.list
  4. sudo apt-get update && sudo apt-get install elasticsearch

In step 4 the error for sudo apt-get install elasticsearch is:
E: Unable to locate package elasticsearch

sources.list.d/elastic-7.8.list contains:
deb stable main

Here is the error that appears for apt update:

Your assistance is greatly appreciated! Thanks

have you ever check your java version?
Elasticsearch is built using Java, and requires at least Java 8 in order to run.

Java version is 11

The error seems to indicate package elasticsearch cannot be found.
