Yes, but the time taken is to actually calculate the action offered. For a few hundred packages, that can be a couple of hours. I expect installation to take a significant time. I recall giving up once after about six hours, but I can't recall how many packages were involved. It was a first unstable upgrade in about six months, I try not to let it go that long, and upgrade my unstable workstation almost every day. -- Joe
