I have a problem with the "Add/Remove software" and the "Software Updater" , in the 2 programs appears the same error: "Unable to retrieve software information" and i can't install any rpm file because appears the same error. If i use "Yum Extender" appears a different error:"Cannot find a valid baseurl for repo: nr-mono" but the same objective, can't update system. help me people i don't know what to do. thanks

Your configuration for the "nr-mono" repository is pointing to the wrong 
place (baseurl or mirrorlist entry is wrong). Check your configuration 
file (either /etc/yum.conf or a .repo file in /etc/yum.repos.d).
