[jzmendo]

Hi. Everybody

I have a problema when i try to install any package or update my system.

My system is Centos 7.7

# cat os-release
NAME="CentOS Linux"
VERSION="7 (Core)"
ID="centos"
ID_LIKE="rhel fedora"
VERSION_ID="7"
PRETTY_NAME="CentOS Linux 7 (Core)"
ANSI_COLOR="0;31"
CPE_NAME="cpe:/o:centos:centos:7"
HOME_URL="https://www.centos.org/"

CENTOS_MANTISBT_PROJECT="CentOS-7"
CENTOS_MANTISBT_PROJECT_VERSION="7"

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. Run the command with the repository temporarily disabled
yum --disablerepo=<repoid> ...

4. Disable the repository permanently, 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>
or
subscription-manager repos --disable=<repoid>

5. 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

I hope somebody can help me with this problem i have 4 days working with this and cannot find the solution.

My system is Centos 7.7

So you need to address that urgently as 7.7 is more than 2 years out of date but you cannot do that until you can fix the current problem.

Is this system behind a web proxy? That's the usual cause of that sort of error, a badly configured or performing proxy sitting between you and the internet and stopping traffic from flowing. You could also try editing /etc/yum/pluginconf.d/fastestmirror.conf and setting "enabled=0" so that the useless plugin gets out of the way.

[jzmendo]

Hi Trevorth Thanks for your answer.

I apply your recomendation but still have the problem.

I changed the variable enabled the value 1 to 0 and try to update with yum and send me the same error.

Let me tell you something i installed another centos 7.7 in my laptop with virtualbox just to use it to make tests
and this distro 7.7 let me update i run yum updat ans let me update.

So with this test, i think i must update the system too under 7.7 may be is a problem with yum or ntwork i dont know

What do you see if you run curl directly like curl "http://mirrorlist.centos.org/?release=7 ... nfra=stock" (quotes required round the url).

[jzmendo]

Hi . TrevorH

This is the output of the comand curl.

This are the repos files i have creted.

You created? All but one look like content from CentOS packages.

You can get mirrorlist with curl. This is what I would try:

Code: Select all

$ sudo yum install http://ftp.osuosl.org/pub/centos/7.9.2009/updates/x86_64/Packages/centos-release-7-9.2009.1.el7.centos.x86_64.rpm
$ sudo yum --enablerepo=* clean all
$ sudo yum repolist

There are two points of interest:
1. Does the yum install create "*.rpmnew" files in /etc/yum.repos.d? If it does, then you have to replace your versions with those.
2. What does the repolist show?

[jzmendo]

Hi jlehtone.

Thank you very much for your answer.

My system has a Centos 7.7 i think this version is out of date.

If you need more information just let me know.

[jlehtone]

You had already shown what you have and that the mirrorlist that you get has issues.

The question is, can you install the package in the URL and what does repolist show after installing that package?

[jzmendo]

Hi Jlehtone.

You mean to perform the following steps.?

$ sudo yum install http://ftp.osuosl.org/pub/centos/7.9.20 ... x86_64.rpm
$ sudo yum --enablerepo=* clean all
$ sudo yum repolist
