Issue/Introduction

When attempting to run a LiveUpdate Administrator (LUA) download schedule, an error is encountered stating "The following updates were found missing on source server Symantec LiveUpdate during download:"  followed by a list of missing updates.

 

Environment

Release : 

Component :  LiveUpdate Administrator

Cause

The files are getting blocked by a proxy or firewall.  Most likely, a list of file extensions (.7z, .m30, .m35, etc...) are getting blocked, causing specific LUA download files to be blocked.

Resolution

Configure the proxy or firewall to allow traffic to/from the Symantec LiveUpdate servers.

LiveUpdate source server addresses can be found in the LiveUpdate Administrator under Configure>Source Servers.  The default http address is liveupdate.symantecliveupdate.com.
