Cannot Update Error with CentOS 5

Ascendancy5 · 12-01-2008, 06:49 AM

I keep logging onto my computer and seeing an error that says my computer is not receiving updates. Whenever I click on the icon to get updates, a window comes up and I get an error with the following:

Code:

Unable to retrieve software information. This could be caused by not having a network Connection available.

I know I am connected to the internet because I am on this forum right now posting, so I know that's not the problem. However when I click details, this is what comes up:

Code:

Cannot find a valid baseurl for repo: extras

Anybody have any idea why I can't get updates?

Take a look in your yum repo list, and see if there is something a bit askew in there.

I would, but I don't actually know where to look, though it shames me to say that... I know where my CentOS-Base.repo file is, but I don't think that's what I'm looking for.

Code:

locate CentOS-Base.repo

HTH, HAND

Well here is the code from my CentOS-Base.repo file under the Extras heading. Let me know if anybody can spot the problem, I'm kind of new to this so I am probably overlooking something silly:

Code:

#additional packages that may be useful
[extras]
name=CentOS-5 - Extras
mirrorlist=http://mirrorlist.centos.org/?release=5&arch=i386&repo=extras
#baseurl=http://mirror.centos.org/centos/5/extras/i386/
gpgcheck=1
gpgkey=http://mirror.centos.org/centos/RPM-GPG-KEY-CentOS-5

irishbitte · 12-04-2008, 03:00 PM

Should this:

Code:

#additional packages that may be useful
[extras]
name=CentOS-5 - Extras
mirrorlist=http://mirrorlist.centos.org/?release=5&arch=i386&repo=extras
#baseurl=http://mirror.centos.org/centos/5/extras/i386/
gpgcheck=1
gpgkey=http://mirror.centos.org/centos/RPM-GPG-KEY-CentOS-5

not be:

Code:

#additional packages that may be useful
[extras]
name=CentOS-5 - Extras
baseurl=http://mirrorlist.centos.org/?release=5&arch=i386&repo=extras
#baseurl=http://mirror.centos.org/centos/5/extras/i386/
gpgcheck=1
gpgkey=http://mirror.centos.org/centos/RPM-GPG-KEY-CentOS-5

Take my advice with pinch of salt, not used to playing with CentOS anymore!

No, the mirrorlist is an alternative to baseurl

I don't think its a repo file problem - here's mine for reference.

Code:

[extras]
name=CentOS-$releasever - Extras
mirrorlist=http://mirrorlist.centos.org/?release=$releasever&arch=$basearch&repo=extras
#baseurl=http://mirror.centos.org/centos/$releasever/extras/$basearch/
gpgcheck=1
gpgkey=http://mirror.centos.org/centos/RPM-GPG-KEY-CentOS-5

which looks pretty much the same.

Are you sure you aren't connected to the net via a proxy? That can cause problems.,

Try "yum clean all", then retry.

Failing all tyhat, comment out the mirrorlist and uncomment the baseurl line and see if that works.

Let us know how you go.

edit - did you do an upgrade from CentOS4 by any chance?

hasanatizaz · 12-04-2008, 04:02 PM

please post your regular centos repo file.

Although man yum.conf isn't clear on this, I'm pretty sure that repos are enabled by default if listed.

For example, my extras doesn't have an enabled parameter, but it is used, and I don't see how it would be causing the error the OP is getting.

ok, but where there are multiple repos "enabled " should be used to control them but not where there are mirrors listed, 1 more important thing to note is if you enabled=1 or enabled=0 it won't work until reboot takes place, atleast this is for rhel5.

Ascendancy5 · 12-05-2008, 07:59 AM

Hey guys, thanks for all the support! I just tried a yum clean all and tried doing the updates and got the same message, and I also tried commenting out the mirrorlist and trying to use the baseurl and still got the same message. I'm going to try a restart now and see what will come of it.

geniushasan, why would I be posting my entire CentOS-base.repo file when the error only says it can't find the extras? It's not that I'm doubting you, I guess I just don't fully understand.

If you run the command from a terminal (as root)

Code:

yum check-update

what is the exact output? Just a clue: has something in your network setup changed lately? Maybe your system is behind a proxy?

I entered that code in as root and this is my output:

Code:

Loading "fastestmirror" plugin
Determining fastest mirrors
 * extras: mirror.centos.org
Could not retrieve mirrorlist http://mirrorlist.centos.org/?release=5&arch=i386&repo=updates error was
[Errno 4] IOError: <urlopen error (111, 'Connection refused')>
Error: Cannot find a valid baseurl for repo: updates

I did an su root before, so I definitely ran that as root. I also know that I am behind a proxy, but I have already configured it, or so I think. I may be missing something, though.

EDIT:

I went through and re-configured my proxy settings and I still got an error, but it was a different error. Here's what it says when I went to apply updates for my CentOS system:

Code:

Cannot retrieve repository metadata (repomd.xml) for repository: c5-media. Please verify its path and try again

colucix · 12-08-2008, 07:53 AM

Ok. Definitively a proxy issue. Regarding the c5-media repository, maybe you have the DVD installation media enabled. You can skip it by:

Code:

yum --disablerepo=c5-media check-update

or eventually just insert the installation DVD if at hand. To disable it permanently, check again the repository configurations under /etc/yum.repo.d
