Centos 7 - Yum update Failed


"yum update" command is not working.
IP information and relevant details below:

-------------------------------------------------------------------------
Here is the error message :
yum update
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/7/x86_64

Steps taken so far :
1. Change to google DNS -->
2. Edited the CentOS-Base.repo file -->
3. Restarted network services -->

Literally I had search all over the place, till now i could not fix the issue.
Appreciate if someone come forward and help me to rectify this issue.

What repos do you have install on your system?

Code:
ls -l /etc/yum.repos.d/

that command will be mostly useless
all it will show is the name of files in the folder
NOT!!! if they are turned OFF or turned ON

please use yum
Code:
su -
yum repolist all

also inform us as to what YOU did to the files in that folder

this issue is normally caused by the user manually editing the files in that folder
( some even have used MS's "notepad.exe" on windows to edit these files -- DO NOT do that)

In the area where you type your response there is a pound sign (#) above that area.
Click on the pound sign to post your terminal output in [code][code] tags.

It's easier for us to read in code tags-

When you make a post you have the general box with the white space where you write to us and above that box is a place where you can choose different fonts, a smiley face, and etc.

Click on the icon that is the pound sign (#).

Place your mouse pointer in between the code tags ([CODE]*[CODE] right click (after you've copied what you want)and than paste. Where the star (*) is; is where you place your cursor.

Your Welcome-

Congrads!-

I'm running CentOS 7 too but I don't understand why your repositories are disabled.
I would imagine that the repo's need to be enabled. (guessing) Best to wait for JohnVV and follow his direction.

You might check the network connectivity. If yum can't access the net for some reason it will also fail like this.

YOU DISABLED the software repos


things that are NOT good!!
Base disabled
Extras disabled
Updates disabled

you manually added a file with a BAD url
base/7/x86_64 CentOS-7 - Base enabled: 0

you manually added a file with a BAD url
updates/7/x86_64 CentOS-7 - Updates enabled: 0


then who knows what else you did

as root make a folder in the folder called "backup"
and MOVE every repo file in there
( do not YET delete them just put them in a new folder as a BACK UP )
then there should OLNY be that folder in yum.repo.d folder

then
manually grab the cent release rpm
http://distro.ibiblio.org/centos/7/o...2.8.x86_64.rpm

download it
then you will need to do a FORCE!!!! reinstall ( this rpm has the repo files in it )

Code:
su -
cd To/The/Location/You/Saved/The/RPM 
rpm --force --install centos-release-7-1.1503.el7.centos.2.8.x86_64.rpm
then clean up the database
Code:
su -
yum clean all 
rpm --rebuilddb 
yum update

No, that's normal. Here's the output from my operational CentOS 7 system:

I believe the C7.0.1406 entries are the installation medium.

OP - are you sure the internet is working correctly on your machine? What is the output of "ping www.yahoo.com"?
