I have a FC4 linux box and used yum regularely until approximately a month ago. I have similar issue than Siddharth Seth. When I run yum update I get: Yum Version: 2.4.1 COMMAND: yum Installroot: / Setting up Update Process Setting up repositories Baseurl(s) for repo: ['http://mirrors.kernel.org/fedora/core/4/i386/os/'] Cannot open/read repomd.xml file for repository: base failure: repodata/repomd.xml from base: [Errno 256] No more mirrors to try. Error: failure: repodata/repomd.xml from base: [Errno 256] No more mirrors to try. I also tried the wget proposition made earlier by one member: [root@bularung etc]# wget --inet4-only http://mirrors.kernel.org/fedora/core/4/i386/os/repodata/repomd.xml --10:03:05-- http://mirrors.kernel.org/fedora/core/4/i386/os/repodata/repomd.xml => `repomd.xml.2' Resolving mirrors.kernel.org... 204.152.191.7, 204.152.191.39 Connecting to mirrors.kernel.org|204.152.191.7|:80... connected.

So it works for inet4 but not 6... I'm looking for some help to fix this issue or a pointer to someone who has fixed it already.
