Hi all, I've been fiddling a lot trying to get the proxy to work. I found out that if I create a local repository using wget and remove the proxy information from yum.conf, the "download" still fails because it is trying to use the http_proxy environment variable. With this unset, it is able to update from a local repository. So, I reasoned, maybe there's something that python or yum doesn't like about the standard http://username:password@host:port/ format, so I wrote a wrapper that unsets the environment variables to see if that makes things work. For the record, here is my wrapper (yumwrap): #!/bin/sh http_proxy= HTTP_PROXY= ftp_proxy= FTP_PROXY= yum $1 $2 However, this doesn't help: $ sudo yumwrap update Setting up Update Process Setting up repositories Cannot open/read repomd.xml file for repository: extras failure: repodata/repomd.xml from extras: [Errno 256] No more mirrors to try. Error: failure: repodata/repomd.xml from extras: [Errno 256] No more mirrors to try. But wget (using the environment variables) is perfectly able to retrieve this file: $ sudo wget http://download.fedora.redhat.com/pub/fedora/linux/extras/4/i386/repodata/repomd.xml --16:07:05-- http://download.fedora.redhat.com/pub/fedora/linux/extras/4/i386/repodata/repomd.xml => `repomd.xml' Connecting to 172.16.110.12:80... connected.
