Hi,
I am running DHIS 2 v2.31 using OpenJDK on Ubuntu 18.04.
This was working fine apart from PNG/PDF download (same result as https://community.dhis2.org/t/problem-downloading-dv-as-png-pdf/33594); also no images were showing in Standard Reports.
Installing libjfreechart-java
solved this (I had also installed libfontconfig
but am not sure this was relevant).
I couldn’t see this documented so I thought I would just put it out there.
