If i run the both softs from a shell, i get something else : Cannot find a valid baseurl for repo: development Error: Cannot find a valid baseurl for repo: development But if i use yum, it works. NEVERTHELESS, i must precise that i have to use a proxy. Configuring the proxy directly in yum.conf, doesn't work at all. I have to edit my .bashrc and add those two lines : http_proxy=http://user:passwr@ipaddress:port/ export http_proxy Would it be a way to add proxy information to the both graphical tools, or is there any other way to update my fc5 using graphical mode ? thx !
