[arch-general] kdebase-workspace and kdeplasma-addons-frameworks are in conflict

I have KDE Plasma 5 installed, and it needed kdebase-workspace removed. Today when I try to update the system I get a unresolvable conflict. $ sudo pacman -Su :: Starting full system upgrade... resolving dependencies... looking for inter-conflicts... :: kdebase-workspace and kdeplasma-addons-frameworks are in conflict. Remove kdeplasma-addons-frameworks? [y/N] error: unresolvable package conflicts detected error: failed to prepare transaction (conflicting dependencies) :: kdebase-workspace and kdeplasma-addons-frameworks are in conflict The general question is, how can I see what package is pulling kdebase-workspace? -- damjan
