I have installed Fedora 20 + Windows 7 dual boot device. I tried to upgrade usingfedup --network 21 --product=workstationAfter rebooting, lxpolkit crashed. Now network manager isn't working. I uninstalled NetworkManager and failed to enable default network. I have read that it's possible by using the live CD. Is it possible to restore Fedora 20?
