Dear Matthew, I have configured my proxy settings as mentioned in the webpage. After configuring I just tried to yum list updates. But I am facing the same problem. [root@fslvm6 fsl]# yum list updates Loaded plugins: fastestmirror, refresh-packagekit, security Loading mirror speeds from cached hostfile epel/metalink | 2.8 kB 00:00 * c6-media: * epel: epel.mirror.srv.co.ge * extras: centos-hcm.viettelidc.com.vn * rpmforge: apt.sw.be * updates: centos-hcm.viettelidc.com.vn file:///media/CentOS/repodata/repomd.xml: [Errno 14] Could not open/read file:///media/CentOS/repodata/repomd.xml Trying other mirror. file:///media/cdrecorder/repodata/repomd.xml: [Errno 14] Could not open/read file:///media/cdrecorder/repodata/repomd.xml Trying other mirror. file:///media/cdrom/repodata/repomd.xml: [Errno 14] Could not open/read file:///media/cdrom/repodata/repomd.xml Trying other mirror.
