I have an Ubuntu 9.04 PC behind a corporate firewall and proxy server. This requires that in order to get update-manager to fetch and apply updates, I must set the proxy and authentication settings in the Synaptic network configuration. Once done, I can check for updates and things work smoothly (except I don't get popup notifications of new updates, must manually check periodically).

However, distribution updates just don't show up in update-manager, such as the newly released 9.10 Karmic Koala. I had the same issue in upgrading 8.10 to 9.04 and solved it by downloading and upgrading from the 9.04 ISO.

What do I need to do to upgrade to 9.10 using the standard update-manager UI?

Try to choose a new server. This helped me to get the distribution update.

Under Paketmanager choose Software Sources

Software Sources

Then choose "Download from:" -> "more"

Choose Download Server

In this dialog, execute "Select best server". Ubuntu will try to detect the fastest connection to a bunch of mirrors.

You may want to use update-manager -d to display development release upgrades.

However, you may have problems upgrading from behind a proxy, as there seems to be a bug in update-manager which causes it to ignore proxy settings for distribution upgrades.

Perhaps your update manager isn't set to display distribution updates? Open the Update Manager and find the "Settings" button on the lower left. Flip to the "Updates" tab and check the setting labeled "Release upgrade". It should be set to "Normal releases".
