Hi, I am using yum 2.6.0 on a Fedora Core 5 system. As you can see, my proxy settings are there: [jwi@stujwi ~]$ set | grep proxy http_proxy=http://httpprox.software-ag.de:8080/ https_proxy=http://sslprox.software-ag.de:443/ They also seem to be right: [jwi@stujwi ~]$ wget http://fedora.redhat.com/ --10:56:55-- http://fedora.redhat.com/ => `index.html' Resolving httpprox.software-ag.de... 10.20.40.6, 10.20.40.5 ... (works fine) But yum doesn't work: [jwi@stujwi ~]$ sudo yum update Password: Loading "installonlyn" plugin Running "config" handler for "installonlyn" plugin Yum Version: 2.6.0 COMMAND: yum Installroot: / Setting up Update Process Setting up repositories core [1/3] Cannot find a valid baseurl for repo: core Error: Cannot find a valid baseurl for repo: core tcpdump shows, that the proxy is not being used, but an attempt to contact the HTTP server directly is made. Any ideas? Regards, Jochen -- Whenever you find yourself on the side of the majority, it is time to pause and reflect. (Mark Twain)
