Bonjour, I have asked one question about yum and rpm, and still no answer; I would like to add an information: yum and rpm do not work for root only! If I try, as normal user, rpm -Va it works; if I try the same command as root: no answer and I have to kill the process (Ctrl-C doesn't work) If I use the command yum update as a normal user, it works untill I have to be root to perform the operation. If do the same as root yum hangs and I have to kill the process... Who cold give me some information? thank you. -- François Patte Ecole française d'Extrême-Orient - Pune - Inde Université René Descartes - Paris 5 UFR de mathématiques et informatique http://www.math-info.univ-paris5.fr/~patte
