cannot upgrade on linux

[artur9]

I was upgrading from MinimServer 0.7 something to MinimServer 0.8.5.2 to get my MinimStream working again.

After reinstalling
hitting the About box in MinimWatch
hitting Show updates

red text appears in the About box stating
Resource not available: http://minimserver.com/updates/minimserver-8.5-jmpud

Something similar happens when trying to update/install MinimStreamer.
