Untrusted Application Launcher

[WizzerWorks]

After installing Magic Lantern Java2D Studio on an Ubuntu 18.04 LTS 64-bit platform, I get an error when clicking on the desktop application for Magic Lantern Java2D Studio. A dialog panel is displayed saying that the application is an "Untrusted Application Launcher".

How do I workaround this problem?

This bug occurs because the .desktop file is installed as root. The workaround is to change the owner and group permissions on the .desktop file.

For example:

$ sudo chown <user> $HOME/Desktop/Magic\ Lantern\ Java2D\ Studio.desktop
$ sudo chgrp <user> $HOME/Desktop/Magic\ Lantern\ Java2D\ Studio.desktop

Then double-click on the desktop icon and you should see

Select the "Trust and Launch" button to continue launching Magic Lantern Java2D Studio.
