Upgrade 9.10 - Missing packages

[Pascal Francq]

Hi,
When I try to upgrade from 9.04 to 9.
10, and the end, I have the following messages :


Err http://archive.ubuntu.com karmic-proposed/main python-dev 2.6.4-0ubuntu1

Any ideas how to solve the problem (the packages seems to miss on the server) ?
