The Deb package xpdf is no longer available in Ubuntu 20.04.  xpdf is probably no longer needed so if installing from source use the following APT command line:

MySQL no longer supports creating a user as part of the GRANT PRIVILEGES command, which causes problems with EPrints if below version 3.4.2. Therefore, perl_lib/EPrints/Database/mysql.pm needs to be patched.  This can be done by using the [https://raw.githubusercontent.com/eprints/eprints3.4/master/perl_lib/EPrints/Database/mysql.pm latest version of mysql.pm on GitHub] if the Eprints version being installed is under 3.4.2.

N.B. It is assumed that you are installing the latest version of 3.4. Earlier versions may have issues not listed here.

MySQL root user cannot be used

On Ubuntu 18.04 LTS rather than prompting you to set a password for MySQL server when installing this as a dependency, it just installs it without. However, this means on the root user can login to MySQL to add a database. As "epadmin create" runs at the eprints user, this will not be able to create a database for EPrints. The get round this as the root user connect to MySQL (just type "mysql" at the command line) and type the following two commands. You will want to set your own password (i.e. not 'changeme') , you may also want to restrict which databases the eprints user has control over. If you know the "Archive ID" you are going to use. 

CREATE USER 'eprints'@'localhost' IDENTIFIED by 'changeme';
GRANT ALL PRIVILEGES ON *.* TO 'eprints'@'localhost' WITH GRANT OPTION;
