I'm trying to run YUM Update, when I do the following message is displayed:

Loaded plugins: fastestmirror, langpacks


One of the configured repositories failed (Unknown),
and yum doesn't have enough cached data to continue. At this point the only
safe thing yum can do is fail. There are a few ways to work "fix" this:

1. Contact the upstream for the repository and get them to fix the problem.

2. Reconfigure the baseurl/etc. for the repository, to point to a working
upstream. This is most often useful if you are using a newer
distribution release than is supported by the repository (and the
packages for the previous distribution release still work).

3. Disable the repository, so yum won't use it by default. Yum will then
just ignore the repository until you permanently enable it again or use
--enablerepo for temporary usage:

yum-config-manager --disable <repoid>

4. Configure the failing repository to be skipped, if it is unavailable.
Note that yum will try to contact the repo. when it runs most commands,
so will have to try and fail each time (and thus. yum will be be much
slower). If it is a very temporary problem though, this is often a nice
compromise:

yum-config-manager --save --setopt=<repoid>.skip_if_unavailable=true

Cannot find a valid baseurl for repo: base/$releasever/x86_64

I've been working on this for several months now and have not had any success. I read several post and google several articles. Just today I recently turned on IPV6 in and effort to get things working, I've had no luck yet.

Has anyone had this problem and resolved it?

Thanks

What distro are you using? What repository are you trying to access? Have you actually tried each of suggestions 2, 3, and 4?

Isn't this the exact same thing you posted about last month?
http://www.linuxquestions.org/questi...um-4175578751/

You were given suggestions and solutions there. Post #9 by knudfl.

To the comment made by TB0one you are correct I did post the last month. As of this post I have not been able to resolve my reported issue yet. I've tried all of the posted solution and so far no success yet. I discovered over the past month that I had other issues with my CENTOS 7.1 installation. As of this post the only remaining issue is this one. I'm getting the following error message when I try to execute a "YUM Update":

failure: repodata/repomd.xml from base: [Errno 256] No more mirrors to try.
http://mirror.centos.org/centos/7.2....ta/repomd.xml: [Errno 14] HTTP Error 404 - Not Found

Can you provide some insight about what might be happening that's causing the above error? Allow me to apologize for not following correct protocol or offending anyone.

To the RockDoctor I'm running CENTOS 7.1.

I would appreciate any help that I can get.

Thanks

you were informed last month that -- 7.1 is unsupported
the repos moved to " The Vault"

dist upgrade to 7.2 first

or

install the 7.2 repolists
http://mirrors.kernel.org/centos/7.2....10.x86_64.rpm
manually edet ( if needed) any third party repos
then run a update

I checked my version I'm running the following release of CENTOS:

cat /etc/centos-release
CentOS Linux release 7.2.1511 (Core)

When I run sudo Yum --releasever=7.2 upgrade I get the following message below:

Loaded plugins: fastestmirror, langpacks
http://mirror.centos.org/centos/7.2....ta/repomd.xml: [Errno 14] HTTP Error 404 - Not Found
Trying other mirror.

I followed the above instructions and still no success, what am i doing wrong?

That seems to be the issue and as such, either the address/mirror you are using is not right or down. The numbered instructions you posted show what to do as 1) have upstream fix it 2) Reconfigure the url 3) Disable it or 4) configure it to be skipped if it is down. Seems to me the easiest fix would be to pick a different mirror.

using " su -" in case sudo is messed up -- it is not set up by default

please post the output of this

this will give us an idea of the files in the repo folder and if they are on or off

from that we move on to reading EACH *.repo file and see just what each is using


but this error right here SHOULD have been fixed ( unless YOU added it by manually editing the url in the repo file)
by installing or reinstalling the centos-release rpm

that is the WRONG location

this is the correct one for the updates repo
from the"CentOS-Base.repo" in the "centos-release-7-2.1511.el7.centos.2.10.x86_64.rpm"
