Bug Description

On both gutsy and hardy, I'm using ppas to get the latest bzr and bzrtools. However, this blocks partial upgrades for update-manager in both releases.

The problem appears to be that the ppas cannot be authenticated, and u-m is none too smart about what to do next. I'd like to be able at least to tell it to ignore the lacke of authentication for these packages, but there's no way to do this. If that's not reasonable, then Partial Upgrade should not be presented as an option if you can't effectively choose to do so.

Fortunately, normal Install Upgrades continues to work fine.

It would also be nice to get more specific information about what's triggering the Partial Upgrade. My suspicion is the unofficial bzr packages, but then this dead-end is even more frustrating.

Thanks for your bugreport.

update-manager is indeed not very smart about unauthenticated packages. In a ideal world everything would be authenticated. The fact that PPAs are not is unfortunate.

A partial upgrade is always triggered if update-manager can not perform a upgrade without removing packages. The partial upgrade has some safe guards build in to prevent bad things from happening (it will ensure that certain packages like the kernel, nvidia-glx etc) get not removed.

could this be correctly be connected to bug 125103 -- where signing for ppas is discussed

This is a reflection of bug 218086: refusing to upgrade with unsigned packages is ok, but the ui for it is unhelpful.
