Hi - Had been using yum and now I'm trying to use it for the first time in a couple months. I sit behind a firewall so I have a http_proxy env variable defined. My yum version is 1.0.3-1_80. I'm running on RedHat8. This is my yum.conf [root@ yum]# more /etc/yum.conf [main] cachedir=/var/cache/yum debuglevel=0 logfile=/var/log/yum.log pkgpolicy=newest distroverpkg=redhat-release keepalive=0 [base] name=Red Hat Linux $releasever - $basearch - Base baseurl=http://mirror.dulug.duke.edu/pub/yum-repository/redhat/$releasever/$basearch [updates] name=Red Hat Linux $releasever - Updates baseurl=http://mirror.dulug.duke.edu/pub/yum-repository/redhat/updates/$releasever When I try to do any yum commands I get the following - [root@ yum]# yum list Error getting file http://mirror.dulug.duke.edu/pub/yum-repository/redhat/update s/8.0/headers/header.info [Errno 4] IOError: HTTP Error 404: Not Found My proxy allows me to get to the site, if I cut/paste the header.info full http call I can verify the file is there. Why do I get the 404 ? Thanks, Stephen
