[12.04] "List of changes not available yet" for every update

[Robert Spanjaard]

On Xubuntu 12.04, I keep getting this message when select an update:

---
The list of changes is not available yet.

Please use [link to online changelog]
until the changes become available or try again later.
---

This has happened for *every* update for the past two weeks or so.
Anyone else with the same experience?
