[Bug 1310891] [NEW] attempting to trigger upgrade from 13.04 (raring) to 13.10 (saucy) claims that No new release found

[uwe]

Public bug reported:

I'm unable to trigger upgrade from 13.04 to 13.10 , and there is no
obvious error that i'm getting:

I made sure that Prompt is set to normal in /etc/update-manager/release-
upgrades  (also confirmed in the GUI)

apt-get update runs successfully and then do-release-upgrade returns:

No new release found

I've tried to use the main-servers , I've tried running apt-get upgrade
, apt-get dist-upgrade, nothing is changing this behavior.

The GUI software update reports: "the software on this computer is up to
date"

Ubuntu basically fails silently to inform me that there are new
releases, and does not show any issue.

I'm within a fairly simple network, I'm not behind a caching server
(unless there is a transparent one at the ISP or so)
