Solr fails to install:

[KatiRG]

Script setup_solr.sh giving the following error in status_out.txt:

Solr requires java, please install or set JAVA_HOME properly

[KatiRG]

Reason: java is not installed:

$ java -version

Command 'java' not found, but can be installed with:

sudo apt install openjdk-11-jre-headless  # version 11.0.16+8-0ubuntu1~20.04, or
sudo apt install default-jre              # version 2:1.11-72
sudo apt install openjdk-13-jre-headless  # version 13.0.7+5-0ubuntu1~20.04
sudo apt install openjdk-16-jre-headless  # version 16.0.1+9-1~20.04
sudo apt install openjdk-17-jre-headless  # version 17.0.4+8-1~20.04
sudo apt install openjdk-8-jre-headless   # version 8u342-b07-0ubuntu1~20.04

Installing java via sudo apt install openjdk-11-jre-headless allows setup_solr.sh to complete successfully.

Modifying setup_solr.sh to install openjdk-11-jre-headless instead of openjdk-11-jre=11.0.15+10-0ubuntu0.20.04.1 successfully installs Solr and java:
