Ubuntu is a leading Linux distribution. First released in 2004 Ubuntu is based on Debian Linux.
Deep Art Effects can run on any version from 16.04 but newer versions (18.04+) have a broken version of Java 8’s OpenJFX so need some specific older packages from 16.04 to work correctly.
Prior to April 16, 2019 versions of Ubuntu older than 16.04 also worked with Deep Art Effects. On April 16, 2019 Oracle changed the license for Java 8 that resulted in the removal of the versions of Java 8 that worked with, for example, Ubuntu 14.04.
