Description of problem:
If you are in a sshfs directory YUM downloads the packages that you asked it to install, but when is going to install them, yum thinks that the packages should already be installed but when it checks, they are not present. As a result the whole installation fails printing the success of the installation

Version-Release number of selected component (if applicable):
Fedora 15
