Description of problem: Laptop running yum-3.4.3-111.fc19. Ran updates, which included yum-3.4.3-120.fc19. After the update any call to "yum update" resultes in messages such as: Warning: group core does not exist. Warning: group office does not exist. ... I can manually set the groups with "yum group mark remove core" and the message is gone, but this doesn't seem neccessary. Other Fedora 19 systems I use did not require this step. Running "yum group mark convert" has completely messed things up and now "yum update" wants to install every package in Fedora. Version-Release number of selected component (if applicable): yum-3.4.3-120.fc19
