Not sure. I’m investigating now. Compared the /etc/yum.repos.d so far and that’s about it.

I might suggest starting off with a 'yum clean all', then running your query again.

OK Thanks. I try that.

Why am I getting these errors? I installed 6.4 in virtualbox and the .repo files seem the same, except the 6.3 box didn’t have a fastback.repo file.

Also why is it looking at 6.4 repos above? When I see:

cat /etc/redhat-release CentOS release 6.3 (Final)

i.e., this box is 6.3. Shouldn’t it be looking for 6.3 repo info?

Thanks,

Odd. I did:

service iptables stop

just to check the curl command again and it timed out again????

iptables -L -n -v

shows no rules

service iptables start

iptables -L -n -v

shows rules again…

I fixed the problem for now by editing /etc/yum.repos.d/CentOS-Base.repy, commenting out:

mirrorlist=

then finding a local university that has /6/ repo data and uncommenting and using:

baseurl=

I’m not sure why this box was having issues reaching mirrorlist.centos.org http://mirrorlist.centos.org/ or even tracerouting to it???? It kept getting a different trace than my 6.4 virtualbox.

I finally just did yum update on this box (actually 6.3) and now it is 6.7. During the update it created a CentOS-Base.repo.rpmnew file. I renamed my current one and this one to just .repo and now I again get:

I thought updating to 6.7 might fix something, but it didn’t help. Any ideas why it is doing this?

Hi,

I wasn't sure if I should reply to you as you seem to be doing a pretty good job of helping your self here :-D.

But jokes aside, can you do a couple of checks?

Firstly, let's make sure this machine actually has a network connection I've actually seen people spend hours trying to fix issues like yours only to find they had no outside network connection..

$ ping 8.8.8.8

Do you get a ping response? If not, check network settings. If you do, move on..

$ ping google.com

Does the domain resolve correctly? If not, check DNS settings. If you do, move on..

Assuming both of those have worked, can you do the following:

$ mkdir temporary $ cd temporary $ wget "http://mirrorlist.centos.org/?release=6&arch=x86_64&repo=os&infr..."

(Don't miss those quotes on the url, they are needed to ensure the &'s do not confuse BASH/ZSH)

Now, what happened? Did it connect and download correctly? If so do the following:

$ cat index.html?release=6&arch=x86_64&repo=os&infra=stock

You should basically get the mirror list:

http://mirrors.coreix.net/centos/6.7/os/x86_64/ http://centos.serverspace.co.uk/centos/6.7/os/x86_64/ http://mirrors.melbourne.co.uk/sites/ftp.centos.org/centos/6.7/os/x86_64/ http://mirrors.vooservers.com/centos/6.7/os/x86_64/ http://mirror.mhd.uk.as44574.net/mirror.centos.org/6.7/os/x86_64/ http://www.mirrorservice.org/sites/mirror.centos.org/6.7/os/x86_64/ http://mirrors.clouvider.net/CentOS/6.7/os/x86_64/ http://mirrors.ukfast.co.uk/sites/ftp.centos.org/6.7/os/x86_64/ http://mirror.cov.ukservers.com/centos/6.7/os/x86_64/ http://mirror.as29550.net/mirror.centos.org/6.7/os/x86_64/

With all of the above checks did you get expecting results including domain resolution, ping response and the mirror list contents?

Yes dns works. If I change this file

/etc/yum.repos.d/CentOS-Base.repo

to this:

[base] name=CentOS-$releasever - Base #mirrorlist=http://mirrorlist.centos.org/?release=$releasever&arch=$basearch&rep...

finally something I can check for you my 6.x machine does not have the trailing &infra=$infra suggest you remove and try again

baseurl=http://some.mirror.in.my.state/centos/$releasever/os/$basearch/ gpgcheck=1 gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-6 file:///etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-6

it works to do updates (and the other baseurl lines in that file). It fails with the mirror list option.

I have a centos 6.2 box here that is working just fine with updates and it looks very similar to this 6.7 box - updated from 6.3). I even tried going from static IP to dhcp assigned IP but no go.

I just check /var/log/yum.log, but that doesn’t show any errors, just successful updates.

Error: Cannot retrieve repository metadata (repomd.xml) for repository: base. Please verify its path and try again

Not sure what to try next. Other than my previous fix of not using a mirror list, but a known local repo that works fine for updates.

-wes

Poking around I found:

/etc/yum/pluginconf.d and now I see where presto comes from. I noticed in the fastmirror.conf there is a line

hostfile-timedhosts.txt

On my test box it has several lines of hosts with a number.

On the box I’m have yum update issues, it is blank. ??

Hi,

I wasn't sure if I should reply to you as you seem to be doing a pretty good job of helping your self here :-D.

But jokes aside, can you do a couple of checks?

Firstly, let's make sure this machine actually has a network connection I've actually seen people spend hours trying to fix issues like yours only to find they had no outside network connection..

$ ping 8.8.8.8

Do you get a ping response? If not, check network settings. If you do, move on..

$ ping google.com

Does the domain resolve correctly? If not, check DNS settings. If you do, move on..

Assuming both of those have worked, can you do the following:

$ mkdir temporary $ cd temporary $ wget "http://mirrorlist.centos.org/?release=6&arch=x86_64&repo=os&infr..."

(Don't miss those quotes on the url, they are needed to ensure the &'s do not confuse BASH/ZSH)

Now, what happened? Did it connect and download correctly? If so do the following:

$ cat index.html?release=6&arch=x86_64&repo=os&infra=stock

You should basically get the mirror list:

http://mirrors.coreix.net/centos/6.7/os/x86_64/ http://centos.serverspace.co.uk/centos/6.7/os/x86_64/ http://mirrors.melbourne.co.uk/sites/ftp.centos.org/centos/6.7/os/x86_64/ http://mirrors.vooservers.com/centos/6.7/os/x86_64/ http://mirror.mhd.uk.as44574.net/mirror.centos.org/6.7/os/x86_64/ http://www.mirrorservice.org/sites/mirror.centos.org/6.7/os/x86_64/ http://mirrors.clouvider.net/CentOS/6.7/os/x86_64/ http://mirrors.ukfast.co.uk/sites/ftp.centos.org/6.7/os/x86_64/ http://mirror.cov.ukservers.com/centos/6.7/os/x86_64/ http://mirror.as29550.net/mirror.centos.org/6.7/os/x86_64/

With all of the above checks did you get expecting results including domain resolution, ping response and the mirror list contents?

Yes dns works. If I change this file

/etc/yum.repos.d/CentOS-Base.repo

to this:

[base] name=CentOS-$releasever - Base #mirrorlist=http://mirrorlist.centos.org/?release=$releasever&arch=$basearch&rep... baseurl=http://some.mirror.in.my.state/centos/$releasever/os/$basearch/ gpgcheck=1 gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-6 file:///etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-6 <file:///etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-6 file:///etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-6>

it works to do updates (and the other baseurl lines in that file). It fails with the mirror list option.

I have a centos 6.2 box here that is working just fine with updates and it looks very similar to this 6.7 box - updated from 6.3). I even tried going from static IP to dhcp assigned IP but no go.

I just check /var/log/yum.log, but that doesn’t show any errors, just successful updates.

What about the other thing he asked you to do:

wget "http://mirrorlist.centos.org/?release=6&arch=x86_64&repo=os&infr... http://mirrorlist.centos.org/?release=6&arch=x86_64&repo=os&infra=stock"

Or even:

nslookup mirrorlist.centos.org http://mirrorlist.centos.org/

nslookup works:

Non-authoritative answer: Name: mirrorlist.centos.org Address: 108.61.16.227 Name: mirrorlist.centos.org Address: 84.22.180.89 Name: mirrorlist.centos.org Address: 88.150.173.218

but wget fails??

$ wget "http://mirrorlist.centos.org/?release=6&arch=x86_64&repo=os&infr..." --2015-12-08 08:04:15-- http://mirrorlist.centos.org/?release=6&arch=x86_64&repo=os&infr... Resolving mirrorlist.centos.org... 199.187.126.90 Connecting to mirrorlist.centos.org|199.187.126.90|:80... failed: Connection timed out. Retrying.

On my centos 6.2 box, wget fails also, but yum update works fine.

Bad http proxy in the way?

Tru

Good point. When I do wget on a working repo (a working local repo in a US state), it works fine, but it errors out on the mirrorlist.centos.org, which is odd.

I don’t need a proxy for this box, but is there a proxy file for wget that is fouling things up? I’ll check.

Thanks,

I just tried wget on my virtual box vm and it shows:

wget "http://mirrorlist.centos.org/?release=6&arch=x86_64&repo=os" --2015-12-08 09:12:33-- http://mirrorlist.centos.org/?release=6&arch=x86_64&repo=os Resolving mirrorlist.centos.org... 108.61.16.227, 84.22.180.89, 88.150.173.218, ...

Why is wget resolving to 199.187….. on these other systems?

and nslookup shows the correct host resolution:

$ nslookup mirrorlist.centos.org

Thanks,

You wouldn't happen to have an entry for mirrorlist.centos.org in your /etc/hosts file for some reason?

Also, what is on the line for the (uncommented out) "hosts:" entry in your /etc/nsswitch.conf file?

I also checked to see if I had a .wgetrc - nope and the /etc/wgetrc file, all the lines are commented out.

I finally just did yum update on this box (actually 6.3) and now it is 6.7. During the update it created a CentOS-Base.repo.rpmnew file. I renamed my current one and this one to just .repo and now I again get:

Error: Cannot find a valid baseurl for repo: base

Loaded plugins: fastestmirror, presto

So maybe the presto plugin is causing the problem. Anyone else using presto plugin??

I use presto without problems. You can try disabling any plugin by going to /etc/yum/pluginconf.d and in the files there, change enabled from 1 to 0
