I had a similar problem before when after many frustrating hours, was the cause of a proxy setting in the env. try env command and look for HTTP_PROXY environment variable. If there is something there, then that maybe your problem. try unset that and rerun yum and see what happens. another test is to try connect to an ftp server using terminal ftp client. That also throws error as it seems to read the same env varibles used to defin a proxy as yum does. The different is it provides better error message which helped me in the original situation. If it is the case, the next daunting task is to figure out what script is setting the env variable :D also i think there are two env varibles one uppercase and one lowercase. Hope that helps <div>On 2/14/06, Antonio Montagnani <<a href="mailto:anto.montagnani@virgilio.it">anto.montagnani@virgilio.it</a>> wrote:<blockquote class="gmail_quote" style="border-left: 1px solid rgb(204, 204, 204); margin: 0pt 0pt 0pt 0.8ex; padding-left: 1ex;"> Paul Howarth ha scritto / said the following il giorno/on 13/02/2006 17:10: > Antonio Montagnani wrote: >> Antonio Montagnani wrote / ha scritto on /il 13/02/2006 09:49: >> >>> Thomas Springer ha scritto / wrote il / on 12/02/2006 22:11: >>> >>>> Am Sonntag, den 12.02.2006, 20:22 +0100 schrieb Antonio Montagnani: >>>> >>>>> Tomorrow morning I will check the contents of /etc/yum.repo.d >>>>> files and if corrupted I will copy from the working machine to the >>>>> router (it should be no problem): any other configuration file to >>>>> check? >>>>> >>>> >>>> >>>> Maybe an increased errlevel will reveal sth of interest: >>>> $ yum -d 9 -e 9 update >>>> See yum manpage. >>>> >>>> >>>> Thomas >>>> >>> >>> yum -d 10 -e 10 update >>> Yum Version: 2.4.1 >>> COMMAND: yum -d 10 -e 10 >>> Installroot: / >>> Setting up Update Process >>> Setting up repositories >>> Cannot find a valid baseurl for repo: updates-released >>> Error: Cannot find a valid baseurl for repo: updates-released >>> >>> I checked also yum configuration files and they seem o.k. >>> What about $basearch or $releasever broken?? how do I see their value?? >>> >> I moved all *.repo files from working machine to my broken machine >> and also yum.conf . >> Results didn't change. >> >> I made another test using only this base repo file : >> >> [base] >> name=Fedora Core $releasever - $basearch - Base >> baseurl=<a href="http://download.fedora.redhat.com/pub/fedora/linux/core/$releasever/$basearch/os/">http://download.fedora.redhat.com/pub/fedora/linux/core/$releasever/$basearch/os/ </a> >> >> #mirrorlist=<a href="http://fedora.redhat.com/download/mirrors/fedora-core-$releasever">http://fedora.redhat.com/download/mirrors/fedora-core-$releasever</a> >> >> enabled=1 >> gpgcheck=1 >> gpgkey=<a href="file:///etc/pki/rpm-gpg/RPM-GPG-KEY-fedora">file:///etc/pki/rpm-gpg/RPM-GPG-KEY-fedora</a> >> >> and I got this result: >> >> yum -d 9 -e 9 update >> Yum Version: 2.4.1 >> COMMAND: yum -d 9 -e 9 >> Installroot: / >> Setting up Update Process >> Setting up repositories >> Baseurl(s) for repo: >> ['<a href="http://download.fedora.redhat.com/pub/fedora/linux/core/4"> http://download.fedora.redhat.com/pub/fedora/linux/core/4</a> /i386/os/'] >> <a href="http://download.fedora.redhat.com/pub/fedora/linux/core/4/i386/os/repodata/repom">http://download.fedora.redhat.com/pub/fedora/linux/core/4/i386/os/repodata/repom </a> >> d.xml: [Errno 4] IOError: <urlopen error (2, 'No such file or >> directory')> >> Trying other mirror. >> 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. >> >> >> Any hint? > > Perhaps the broken machine has a proxy configured in the environment > or in /etc/yum.conf, and that proxy is broken? > > Paul. > This is my yum.conf file.I am surprised because the machine was running fine until thursday night.How can I check if a proxy has been configured in the enviroment?
