The documentation indicates: Jaspersoft 7.8.0 / 8.1.1 requires you to install Chrome Xxx or higher release on the server where you plan to install Jaspersoft
Why is Chrome/Chromium engine installation required on the server where Jaspersoft will be running? Can the upgrade can be completed without installing it / any alternatives?
Due to security, you may not be able to download and install Chrome on our Linux servers without approval from your Linux administrator
Release : Jaspersoft 7.8, Jaspersoft 8.1
Starting Jaspersoft 7.8. PhantomJS has been deprecated and replaced with the Chrome engine, which is used to render any HTML 5 or fusion charts-based reports and dashboard. Because of this, it is required to have Google Chrome browser installed on the Jaspersoft server. Without specifying it, the Jaspersoft install/upgrade will not work.
