Is it OK to remove dnf with yum remove dnf ? will it cause any problems ?
If you upgrade from F19 to F20 dnf will not be installed, so I see no harm in removing it from F20.
yum is the main tool to use, dnf is installed to be tested.
Should I remove rpmfusion-free-rawhide?
After a fresh installation of fedora 20, I can only log 1 time as a su. After, it is refused for authentification error!
Network Manager won't let me do that, and the command-line tools I used back in the older versions of Fedora don't seem to exist any more.
Any idea why yum doesn't show by default from what mirror it is downloading from?
