Description of problem:

When the customer selects hosts on which they want to install errata, and they use the upper-right menu to try to install errata on those hosts, they can only install errata that appear on the current page of available errata.  If they move to the next page, they can install those errata instead.  However, when they select the option to install all errata, then Satellite gives them this error message:

Bad Gateway
The proxy server received an invalid response from an upstream server.

How reproducible:

100%

Is this issue a regression from an earlier version:

Yes.

Steps to Reproduce:

1.  log into the web interface of the satellite server

2.  click on the hosts menu on the left side of the page

3.  click on "Content Hosts"

4.  select the desired hosts

5.  click on the "Select Action" menu in the upper-right corner of the page

6.  select "Manage Errata"

7.  click on the check-mark box in the upper-left corner of the table to select all items on the current page

8.  click on the link "Select all NNN".

9.  click the "Install Selected" button in the upper-right corner.

10.  click the Yes button at the top of the page

Actual behavior:
The remote execution for this choice will fail.

Expected behavior:
The remote execution for this choice should succeed.

Business Impact / Additional info:

The workaround (to install only the visible page of errata at a time) is not obvious to customers, and for large environments can be burdensome.
