[Michiel van Es]

Hi,

When I try to install a scheduled update I get the following error:

Summary:	Package Install scheduled by admin
Details:	This action will be executed after 03/16/10 5:19:51 AM CET.

This action's status is: Failed.
The client picked up this action on 03/16/10 5:20:00 AM CET.
The client completed this action on 03/16/10 5:20:02 AM CET.

It happens on ALL my CentOS 5 machines.
DOes anyone know why this happens?
As you can see it see's some scheduled updates but fails to install them 
with the message: No package(s) available to install" (code 32)

Sounds like a contradiction to me :)
