Yeah…the Linux Fixlets that use download plug-ins are a bit more complicated. This doesn’t necessarily mean there’s actually a syntax error in the Fixlet, but that the dependency resolution that runs to generate the package dependency download list is failing.
That can happen if the debianpackage installations are inconsistent, or packagelock is blocking a package upgrade, or probably a few other things.
At that point there should be some useful in at /var/opt/BESClient/EDRDeployData or related EDR directories.
If there’s nothing obvious in those logs, we can step through it with you in a support ticket
