I am running yum-2.0.3-5.rh.fr on redhat 8.0. Everytime I run "yum check-update", I got the error message "Existing lock /var/run/yum.pid: another copy is running. Aborting." . Actually, I got the same error message on ALL yum command except the help command "yum -h". After searching from web, I got some hints http://www.fedoraforum.org/forum/showthread/t-900.html but that didn't solve my problem. I am sure: 1) I am running as root 2) there are no other copy of yum running 3) the file /var/run/yum.pid doesn't exist I have read thru the documentation. Anyone could give me a hand? Thanks in advanced. Bill
