Due to a server crash last night, I'm temporarily setting up my workstation as a mail server. To that end, I'm trying to install some rpms for clamav. I tried the normal rpm install: rpm -Uvh <rpm name> and it seemed to hang. I terminated the shell in which this was running, and tried again, and got the following: warning: waiting for transaction lock error: can't create transaction lock The process that was running the original rpm is still around, even when trying to kill-9 it: root 31879 1 0 09:15 ? 00:00:00 rpm -Uvh clamav-0.74-1.i386.rpm Any thoughts on: 1) How to kill the previous process when kill -9 doesn't? 2) Any other way to get this rpm to install? TIA, -Don
