Problem with installing LibrePlan

Question

I am trying to install LibrePlan on Ubuntu 18.04, the instructions say that I should run

sudo add-apt-repository ppa:libreplan/ppa
sudo apt-get update
sudo apt-get install libreplan

But on the first command i get this:

LibrePlan (aka NavalPlan) is a free software web application for     
project management. It is written in Java and licensed under 
AGPLlicense.

E: The repository 'http://ppa.launchpad.net/libreplan/ppa/ubuntu bionic Release' does not have a Release file.
N: Updating from such a repository can't be done securely, and is therefore disabled by default.
N: See apt-secure(8) manpage for repository creation and user configuration details.

I see that the url http://ppa.launchpad.net/libreplan/ppa/ubuntu points to a repository containing "dists" which is not containing bionic folder is that the problem? Simply the package for Ubuntu 18.04 is not ready (if I use the word package correctly) ?

In addition I've tried to add the key B4BE203D09B8AF1F528B8D1054CAAB19DE395C80 with sudo apt-key add key.txt but the following error occured gpg: no valid OpenPGP data found. The key is located at https://launchpad.net/~libreplan

libreplan has not been maintained since 15.04 (Vivid) http://ppa.launchpad.net/libreplan/ppa/ubuntu/dists/ Best to probably contact Libreplan themselves about this: http://www.libreplan.org/ — Terrance, Aug 19 '18 at 15:08

Got it working on both Ubuntu 18.04 and 20.04 by adding some additional steps to the original guide:

Install requirements:

apt-get install git-core maven openjdk-8-jdk postgresql postgresql-client python-docutils make gettext cutycapt

Set default JDK:

update-java-alternatives -s java-1.8.0-openjdk-amd64

Connect to database:

su postgres -c psql

Use SQL sentences:

CREATE DATABASE libreplandev;
CREATE DATABASE libreplandevtest;
CREATE USER libreplan WITH PASSWORD 'libreplan';
GRANT ALL PRIVILEGES ON DATABASE libreplandev TO libreplan;
GRANT ALL PRIVILEGES ON DATABASE libreplandevtest TO libreplan;

Download source code:

git clone git://github.com/LibrePlan/libreplan.git

Add missing dependency to the end of libreplan/libreplan-webapp/pom.xml:

<dependency>
    <groupId>org.olap4j</groupId>
    <artifactId>olap4j</artifactId>
    <version>1.2.0</version>
</dependency>

Compile project but skip tests:

cd libreplan/
mvn -DskipTests clean install

Launch application:

cd libreplan-webapp/
mvn jetty:run

Go to http://localhost:8080/
