We use Xubuntu 20.04 LTS for the installation of DSpace 6. ISO file of the operating system can be downloaded from the Xubuntu website, https://xubuntu.org/release/20-04. No problem using other Ubuntu flavors (e.g. Ubuntu with GNOME, KDE, Lubuntu) for the installation. Either burn the ISO file to a pen drive or DVD. Install the Xubuntu on the machine. Create a user account during the installation (e.g. mgu). Create the user with the name dspace after the installation of Linux based operating system. If you have already run on Ubuntu/Debian (e.g. for Koha), create a dspace user.
Keep in mind that Support for DSpace 5 and 6 is ending in 2023.
Prepare the system for Dspace installation.
DSpace builds on the Java platform and it requires a set of software packages like Tomcat, Solr, Maven, Ant, etc. Install the prerequisites for the Dspace software.
