[02:25] <duflu> RAOF: Oh, you can't apt remove automatically installed packages?
[02:25] <duflu> It's like they're not installed
[03:11] <RAOF> duflu: ??
[03:11] <RAOF> I'm not sure what you mean. “sudo apt autoremove” just removed a bunch of automatically installed packages here.
[03:17] <duflu> RAOF: Yeah that works. But before then they don't show up in dpkg -l or apt remove <name>
[03:18] <duflu> So you can't see that you've got stale packages installed other than searching for their files
[03:18] <RAOF> I still don't see that behaviour :)
[03:19] <duflu> PPAs are evil
[03:19] <duflu> I have removed them now
[03:19] <RAOF> apt upgrade, for example, lists all the automatic-but-no-longer-necessary packages I had installed.
[03:19] <duflu> RAOF: Yes indeed. But dpkg -l or an explicit apt remove <name> doesn't show them
[03:20] <duflu> Never mind. All gone
[03:20] <RAOF> Extremely odd. I don't know how you've managed to mess your dpkg database up to such an extent :)
[03:21] <duflu> Add one PPA
[03:21] <duflu> that's it
[03:28]  * RAOF feels tempted to write mir::aggregate_error
[04:22] <RAOF> Urgh. How has this git tree got messed up?
[05:40] <duflu> RAOF: Cosmic rays. Must be affecting both sides of the country
[05:41] <duflu> Sun spots
[05:41] <duflu> Bad luck
