Re: [CentOS] CentOS 6 update issues

[John Cenile]

Hello Johnny,

That appears to be it, our network DNS resolvers were caching an old record
from the looks of it.

I've cleared the cache, and everything is now working perfectly.

Thank you (all) for the help, I wasn't even aware that the 204.15.73.243
address was no longer valid.

I don't think so on our end, but that was at one time a good address.

Maybe the site in question has a static address added in a hosts file, etc.

204.15.73.243 reverse resolves to centos.at.multacom.com.
multacom is a CentOS Sponsor according to:
https://www.centos.org/sponsors/

An outdated config somewhere?

Those 3 addresses are good, the 204.15.73.243 is incorrect.

Yes, that address is not listed in our DNS zone file for mirrorlist.  In
fact, that address is not in our zone file for anything .. so I have no
idea where you are getting it looked up from.

Re: [CentOS] CentOS 6 update issues

[John Cenile]

I'm actually not able to connect to that host:

# curl "http://mirrorlist.centos.org/?release=6&arch=x86_64&repo=extras";
curl: (7) couldn't connect to host


Which lead me to discover that our entire network is picking up "
mirrorlist.centos.org" as 204.15.73.243, which I'm not able to ping from
any host in a few different countries I tried.

However, if I ping mirrorlist.centos.org from Europe, it resolves
to 84.22.180.89, or from USA it resolves to 88.150.173.218, or from Asia it
resolves to 108.61.16.227.

Could there be an issue with this specific mirrorlist server
(204.15.73.243)?

What does this command give you from that machine:

curl "http://mirrorlist.centos.org/?release=6&arch=x86_64&repo=extras";

Are you using ipv4 or ipv6?

Re: [CentOS] CentOS 6 update issues

Thanks for the suggestions, unfortunately that file doesn't exist.

I'm very confused as to why it's trying to download from /6.6/.

The output of rpm -qi centos-release-6-4.el6.centos.10.x86_64 is:

In your initial post you mentioned problems with extras. Here you are 
changing the stanza of base.

What is your stanza for "extras"?

Have you manually set releasever in your yum config?

As a short term fix, maybe you should.

I had something similar happen recently when upgrading a box from 6.6 to 6.7

I 'fixed' it by running 'yum clean all' first

I did think it odd at the time - but didn't get round to trying to find out why 
...

Hi, in most cases you would expect mirrorlist to be defined rather than
baseurl  unless you want to be pointing to a specific repository.
I would suggest that you do a fresh install somewhere update it and then
compare the files in /etc/yum.repos.d/ with your existing systems.

As examples of base and updates from one of my own systems I have

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

#released updates
[updates]
name=CentOS-$releasever - Updates
mirrorlist=
http://mirrorlist.centos.org/?release=$releasever&arch=$basearch&repo=updates&infra=$infra
#baseurl=http://mirror.centos.org/centos/$releasever/updates/$basearch/
gpgcheck=1
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-6
