Hi,
I upgraded ArcGIS for Server and WebAdaptor on a Linux machine to 10.3.1. I downloaded the latest Patchfinder I can find, e.g. here
ArcGIS 10.3.1 for Server (Linux) WMS GetCapabilities Patch | Samples and Utilities
at the bottom of the page.
Running PatchFinder does not show the releases installed. It seems that it is still an old version.
Is there a newer version around ?
