jenkinsci docker install-plugins.sh fails build

I am trying to package the vanilla Jenkins image into Docker using this tutorial: https://github.com/jenkinsci/jenkinsfile-runner/blob/master/DOCKER.md Everything works until one of the last steps where the Dockerfile tries to run install-plugins.sh from a plugins.txt file that was just copeid into its own directory. This is the error I am getting when running docker build:

/usr/local/bin/install-plugins.sh: line 148: TEMP_ALREADY_INSTALLED: unbound variable
The command '/bin/sh -c /usr/local/bin/install-plugins.sh < /usr/share/jenkins/ref/plugins.txt' returned a non-zero code: 1

Here is my plugins.txt file:

pipeline-model-definition:latest

Just the one line.

I cannot seem to figure out what might fix this issue. I tried using the suggestion from this answer here: https://github.com/jenkinsci/docker/issues/348 but the command line spat out the exact same error as above. Any help is appreciated, thanks in advance.

That variable was defined in plugins.sh (which is deprecated and supposed to be replaced by install-plugins.sh)

# the war includes a # of plugins, to make the build efficient filter out
# the plugins so we dont install 2x - there about 17!
if [ -d "$JENKINS_HOME" ]
then
    TEMP_ALREADY_INSTALLED=$JENKINS_HOME/preinstalled.plugins.$$.txt
else
    echo "ERROR $JENKINS_HOME not found"
    exit 1
fi

But it is not defined in install-plugins.sh, only used (in line 155)

Try and set TEMP_ALREADY_INSTALLED first, as shown above, before calling install-plugins.sh.
