Yum updater does not work, no repolist on my CentOS system.

Good day all.

I've installed CentOS 7 on a VM without any noticeable problems. However, when trying to update the system, I found that yum updater does not work. It seems I do not have any repos defined.

Code:

[root@centos7 brh]# yum check-update

Loaded plugins: fastestmirror, langpacks

Loading mirror speeds from cached hostfile

There are no enabled repos.

 Run "yum repolist all" to see the repos you have.

 You can enable repos with yum-config-manager --enable <repo>

No repos:

Code:

[root@centos7 brh]# yum repolist all

Loaded plugins: fastestmirror, langpacks

Loading mirror speeds from cached hostfile

Also,my yum.conf has no repo mirrors defined:

Code:

[root@centos7 brh]# cat /etc/yum.conf

[main]

cachedir=/var/cache/yum/$basearch/$releasever

keepcache=0

debuglevel=2

logfile=/var/log/yum.log

exactarch=1

obsoletes=1

gpgcheck=1

plugins=1

installonly_limit=5

bugtracker_url=http://bugs.centos.org/set_project.php?project_id=23&ref=http://bugs.centos.org/bug_report_page.php?category=yum

distroverpkg=centos-release





#  This is the default, if you make this bigger yum won't see if the metadata

# is newer on the remote and so you'll "gain" the bandwidth of not having to

# download the new metadata and "pay" for it by yum not having correct

# information.

#  It is esp. important, to have correct metadata, for distributions like

# Fedora which don't keep old packages around. If you don't like this checking

# interupting your command line usage, it's much better to have something

# manually check the metadata once an hour (yum-updatesd will do this).

# metadata_expire=90m



# PUT YOUR REPOS HERE OR IN separate files named file.repo

# in /etc/yum.repos.d

How can I get a valid repolist?

Thanks in advance,

Bjoern

You have to enable the EPEL Repo-

@brh1, the repo`s are not defined in /etc/yum.conf . Never.

'yum' will look for repo files in /etc/yum/repos.d/, where the enabled file is CentOS-Base.repo .
Attached as CentOS7-Base.repo.txt .

Extra repo`s : Simply add a file, e.g. 'epel.repo' :
# yum install Downloads/epel-release-7-5.noarch.rpm
https://dl.fedoraproject.org/pub/epe...7-5.noarch.rpm

I made a directory /etc/yum/repos.d and dropped the repo file you attached in it. Here's the yum check-update result:

Code:

[root@centos7 repos.d]# yum check-update

Loaded plugins: fastestmirror, langpacks

Repodata is over 2 weeks old. Install yum-cron? Or run: yum makecache fast

base                                                                                                              | 4.8 kB  00:00:00    

http://mirror.millry.co/CentOS/7.0.1406/os/x86_64/repodata/repomd.xml: [Errno -1] Error importing repomd.xml for base: Damaged repomd.xml file

Trying other mirror.

All the other mirrors failed with Errno -1

I tried your method, downloading the rpm was no problem, but the installation failed:

Sorry it failed.
It may have failed because the extras were disabled?

Try this:

Code:

wget http://dl.fedoraproject.org/pub/epel/7/x86_64/e/epel-release-7-5.noarch.rpm

sudo rpm -Uvh epel-release-7*.rpm

Instructions are in the second link.

There are some indications in your post that some other folders / files are missing in /etc/.
? How did you get your OS messed up ?
( /etc/yum/repos.d/ is always present after the OS install.)

knudfl has a point

WTF

that folder IS!!! a default folder
it WAS made at the time of install
it IS part of the Operation system

it is like saying that "C:\\Program Files (x86)\Common Files" is missing on a windows machine

REINSTALL this severely broken OS

That is correct, there isn't a /etc/yum/repos.d. It changed in version 7. Did anyone read the 1st post?

I assume that yum is working since you reinstalled?

Nope. Now it barfed a different error message:

Code:

[root@localhost brh]# yum check-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

What virtual software are you running i.e. vmware, virtualbox etc.

How did you configure the VM network adapter?

Running on VMware Player v6 and network adapter setup for NAT. I have no issues with this VM on another PC at home. I'll just have to do a 'stare-and-compare' as soon as I get the opportunity.
