APS Installer in mirror setup

[diablo666]

I've a mirror setup of 2 nodes all working ok.

I'm now trying to the APS Installer.

I've lunced the update procedure from the slave and all seems ok, now i can see alle the apps on both servers.

When i try to install an app from the Master i'll get the errore

"The metafile for Drupal couldn't be found"

In my case i've tried to install Druapl.

Now on the master i've lunced the upgrade and all seems to work ok.

The question is, to use APS installer and application, i've to update packages lists on both server? Or APS Installer isn't supported in mirror configuration?

Tnx a lot for response.
