In this context, we shall look into how to install OpenMAINT on Ubuntu 20.04.

Steps to take to successfully install OpenMAINT on Ubuntu

1. Update the system apt package manager

To begin, you need to run apt command to update the packages:

$ sudo apt update

$ sudo apt upgrade

2. Install the Java Development Kit

To install JDK (Java Development Kit), simply Run apt command to install:

$ sudo apt install default-jdk

3. Install PostgreSQL

We recommend using PostgreSQL 10 because PostgreSQL 11 and newer causes OpenMAINT to fail.

i. Run the following commands:

$ wget --quiet -O - https://www.postgresql.org/media/keys/ACCC4CF8.asc | sudo apt-key add -
$ RELEASE=$(lsb_release -cs)
$ echo "deb [arch=amd64] http://apt.postgresql.org/pub/repos/apt/ ${RELEASE}"-pgdg main | sudo tee /etc/apt/sources.list.d/pgdg.list

ii. Next, run the following commands to verify and update:

$ cat /etc/apt/sources.list.d/pgdg.list deb [arch=amd64] http://apt.postgresql.org/pub/repos/apt/ focal-pgdg main
$ sudo apt update

iii. And now, we will install PostgreSQL:

$ sudo apt install postgresql-10 postgresql-contrib

Press Enter.

This will create a user named "postgres". And next, let's set your password:

$ sudo passwd postgres

4. Install PostGis

Run the below apt command to install PostGis:

$ sudo apt install postgis postgresql-10-postgis-3 libpostgis-java

5. Set up PostgreSQL Database Server

Switch to the user "postgres" by running the command:

$ sudo su - postgres

Next, Set the password:

$ psql -d template1 -c "ALTER USER postgres WITH PASSWORD 'linux123';"

Here, Replace "linux123" with a password you want to set. Type "exit" to logout.
