The custom filter options in Synaptic are kind of cryptic to me. I know over the last year and a half (I haven't fresh-installed since 10.04) I've installed several .debs and packages from PPAs.
How can I set up a filter in Synaptic that finds just these packages, so that I can downgrade or remove them?
It's actually not as hard as I thought it might be - and it's probably quite a valuable filter to have!
First you select which status you want to show. I selected "Installed" amongst a couple of others but that's probably all you need.
The real nuts and bolts come from the properties screen. In there you can set the origin requirements. All I did was exclude anything from archive.ubuntu.com (which is the mirror I use). If you're using another mirror, change that string.
The alternative would be to disable all the PPAs in sources and then look at the local section.
