Pacman find lost dependencies

Hi all, I tried to clean up my system today with the command: pacman -Rs $(pacman -Qdttq)

The result is that it wants to uninstall a lot of packages that I need like bluez or plasma-desktop. There must be a bug here or a significant package is missing which makes all these dependencies obsolete.

Is there a way to check which package is missing? To me it looks like it wants to delete the whole system.

pacman -Rs $(pacman -Qdttq)

Re: Pacman find lost dependencies

First off, you probably want to drop the second 't'.

Anything that you specifically want should be explicitly installed. See pacman -D.

Re: Pacman find lost dependencies

Thanks for the reply. I have now removed the second "t". I wonder why it wants to uninstall plasma-desktop.

Re: Pacman find lost dependencies

It wants to uninstall it because it was only installed as a dependency of another package, which you apparently removed at some point. plasma-meta, maybe?

Re: Pacman find lost dependencies

Yes that was my salvation, in fact I uninstalled plasma-meta. Have now cleaned up the system and it works. Thanks a lot and have a nice weekend!
