Hello, please contact your local support representative and open a support ticket, as we were unable to determine the cause of the problem from the info attached.


Also please comment, if you have configured your product, to update via apache http prpxy, or it has direct access to the internet. The same is valid for the ERA server.


Concerning the repository issue, it might happen, that the software install task, you want to run, linked to a package, that is no longer available in the repository (it was replaced with a newer version, for example). I would suggest creating a new software deployment task, and trying it again.

Thank you for reply.


We have a HTTP Apache Proxy in the ERA Server and edited these lines (httpd.conf):

We also have a ERA Proxy in other server.
