Put a blocked package upgrade back to whoever is updating (#6830)
Pacman answers its own conflict question with No under --noconfirm, so one retired package can stop every update after it. Which package to drop is a decision rather than a cleanup, so run the upgrade again with pacman asking when there is a terminal to answer on, and report instead when -y promised not to ask.
