Findiding Source of Packages

In the past, I have been successful in downloading packages via the AREDN mesh network as there has been an internet connection available on the network which I assume can reach the AREDN package server.  In the ADMIN page, I've been able to click the REFRESH button next to DOWNLOAD PACKAGE and all the packages would download successfully.  Then I would choose SNMPD from the DOWNLOAD PACKAGE list then click the DOWNLOAD button.  I would confirm that the package was now listed in the REMOVE PACKAGE list and all is good.

Lately, I'm getting a FAILED TO DOWNLOAD error for most the packages.  I need to install the SNMPD package.

We have not set up a Package server yet.  Is there a way to download the packages from the AREDN website to a folder then install them manually to the node from that folder? 


I can find the SNMPD package on the AREDN website, do I need to install more than just the SNMPD package to make it work?   Just need help on the steps to install the SNMPD package manually.

Thanks
Bob
