Yes, I know, it's a very poor interaction between a bug in synaptic
<https://bugs.launchpad.net/ubuntu/+source/synaptic/+bug/218086> and
the fact that PPAs are not signed
<https://bugs.launchpad.net/soyuz/+bug/125103>. The second bug is
promised to be fixed very soon.

For a regular dist-upgrade you can work around this by running it from
the command line rather than the gui, but I'm not sure if that's
enough for upgrading from one release to the next.
