Hi Rex: I have a new F10 installation and in the past have used the smart package manager, most recently in Centos 5.2. It would not install the F10 k3b and k3b-libs combination because it had - Found unbreakable loops: k3b-1.0.5-6.fc10 at x86_64 [R] -> k3b-libs-1.0.5-6.fc10 at x86_64 [R] -> k3b-1.0.5-6.fc10 at x86_64 [R] Will ask RPM to order it. On clicking 'ok' smart exits. I had a similar problem earlier with some atrpms packages but it didn't persist, perhaps because new packages arrived. 'yum install k3b' had no problems, but I would like to be able to stay with smart. John Pilkington
