Install centreon on centos7.9 raspberrypi - repository

How guys, can you help me I have problem with install centreon:
#yum install centreon-base-config-centreon-engine centreon
output
Loading mirror speeds from cached hostfile
base: mirror.vpsnet.com
centos-kernel: mirror.vpsnet.com

To address this issue please refer to the below wiki article
https://wiki.centos.org/yum-errors
If above article doesn't help to resolve this issue please use https://bugs.centos.org/.
One of the configured repositories failed (Centreon Entreprise Linux reposistory contains software to use with Centreon.),
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=centreon-stable ...
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 centreon-stable
or
subscription-manager repos --disable=centreon-stable
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=centreon-stable.skip_if_unavailable=true
failure: repodata/repomd.xml from centreon-stable: [Errno 256] No more mirrors to try.
http://yum.centreon.com/standard/3.4/el7/stable/armhfp/repodata/repomd.xml: [Errno 14] HTTPS Error 404 - Not Found
What i done is:
ls /etc/yum.repos.d/
nano /etc/yum.repos.d/centreon.repo #enabled=0
Where can i find package for "centreon-base-config-centreon-engine centreon"

The Centreon version 3.4 is not supported anymore.
You should use an newer version.
Latest is the 21.04.
This version comes with a script that does all the install automatically.
It is described in the "Packages" tab of the Centreon download site: https://download.centreon.com/

Kubernetes cluster setup using kubeadm, how to fix peer certificate error

I am setting up kubernetes cluster using kubeadm on on-premise servers (Centos 7.6). I got the "Peer certificate error". I set sslverify=0 in kubernetes.conf and able to proceed. But want to know how to download the certificate and proceed without sslverify flase.

It was impossible to connect to the CentOS servers.
This could mean a connectivity issue in your environment, such as the requirement to configure a proxy,
or a transparent proxy that tampers with TLS security, or an incorrect system clock.

Yum install graphviz on RHEL 7 fails with 'No package graphviz available.'

I am trying to install graphviz on my RHEL VM. when I run
$sudo yum install graphviz
I get this:
This system is not registered with an entitlement server. You can use subscription-manager to register.
No package graphviz available.
Error: Nothing to do
I later found out that I get this same problem with all packages.
I have tried several solutions I have found online such as:
saving the .repo file found here (this link will download the file)
then running
#from dir containing graphviz-rhel.repo
$sudo yum-config-manager --add-repo graphviz-rhel.repo
the output was
This system is not registered with an entitlement server. You can use subscription-manager to register.
adding repo from: graphviz-rhel.repo
grabbing file graphviz-rhel.repo to /etc/yum.repos.d/graphviz-rhel.repo
repo saved to /etc/yum.repos.d/graphviz-rhel.repo
Then I ran
$sudo yum-config-manager --enable graphviz-rhel
This gives no output and $yum-config-manager list all does not list anything related to graphviz as a repo (enabled or disabled)
I tried the solution here: failed to install 'graphviz*' packages with yum command on my RHEL server
except I found the rpm file here
When I ran the rpm command I got an error because I was missing a couple dozen dependencies so I dont think following this solution for all of them is a reasonable solution.
If someone can either inform me why one of these didn't work or let me know how to accomplish my goal of getting yum install <package> to work I would greatly appreciate it.
As posted in the comments, in order to utilize yum on a RHEL system you need an active subscription

Reinstall rhn-client-tools with non working yum

For every yum command it will return SSL certificate error
Loaded plugins: fastestmirror, rhnplugin, security
The SSL certificate failed verification.
My SSL cert if valid.
I checked rhel site for https://access.redhat.com/solutions/93313 but the problem is i cannot reinstall rhn-client-tools since yum is actually not working and for some other reasons i cannot boot it from DVD/image.
Any tips on this?
Before trying to reinstall, have you also checked your firewall settings and the time and date setting on your server ?
If the firewall is not the issue, I would suggest a simpler approach, just by going to RH's site and downloading the appropriate rhn-client-tools RPM package, copying it to your server and installing it.
"What about the possible dependencies?" I foresee you asking...
Use a different server (or VM) with the same OS version that has access to the internet.
use yum with the download only plugin to only download all the needed dependencies (you must have the yum-plugin-downloadonly package installed beforehand) in a local directory like so:
yum install --downloadonly --downloaddir=<directory> <package>
Copy the packages downloaded at step #2 to your affected machine and install them using the rpm utility as so: rpm -ivh /path/to/yum/download/dir/*

yum update on CentOS complains about "Multilib version problems" of "nss-softokn-freebl"

On last Friday morning, I tried a "yum update" on my CentOS laptop, and it reported this:

--> Finished Dependency Resolution
Error: Multilib version problems found. This often means that the root
cause is something else and multilib version checking is just
pointing out that there is a problem. Eg.:
1. You have an upgrade for nss-softokn-freebl which is missing some
dependency that another package requires. Yum is trying to
solve this by installing an older version of nss-softokn-freebl of the
different architecture. If you exclude the bad architecture
yum will tell you what the root cause is (which package
requires what). You can try redoing the upgrade with
--exclude nss-softokn-freebl.otherarch ... this should give you an error
message showing the root cause of the problem.
2. You have multiple architectures of nss-softokn-freebl installed, but
yum can only see an upgrade for one of those architectures.
If you don't want/need both architectures anymore then you
can remove the one with the missing update and everything
will work.
3. You have duplicate versions of nss-softokn-freebl installed already.
You can use "yum check" to get yum show these errors.
...you can also use --setopt=protected_multilib=false to remove
this checking, however this is almost never the correct thing to
do as something else is very likely to go wrong (often causing
much more problems).
Protected multilib versions: nss-softokn-freebl-3.16.2.3-14.2.el7_2.i686 != nss-softokn-freebl-3.16.2.3-13.el7_1.x86_64
I asked about this on #centos, and someone gave me some exploratory advice, but no real solution.
I experienced the very same issue on a Fedora 20 system (run in a docker container) when trying to install i686 development libraries. Reason were two not matching versions for x86_64 and i686, respectively.
Protected multilib versions: nss-softokn-freebl-3.19.1-1.0.fc20.i686 != nss-softokn-freebl-3.19.2-1.0.fc20.x86_64
For me it helped to call
yum distribution-synchronization
That automatically downgraded the x86_64 version. After that
I could install with
yum install nss-softokn-freebl.i686
and
yum list installed | grep nss-softokn-freebl
showed now:
nss-softokn-freebl.i686 3.19.1-1.0.fc20 #updates
nss-softokn-freebl.x86_64 3.19.1-1.0.fc20 #updates
Problem solved.

CentOS yum 'No package gnuradio available'

I'm installing GNU Radio and following the instruction here
But everytime I try to do sudo yum install gnuradio, it says
Loaded plugins: fastestmirror, refresh-packagekit, security
Loading mirror speeds from cached hostfile
* base: centos.mirror.cdnetworks.com
* extras: centos.mirror.cdnetworks.com

Setting up Install Process
No package gnuradio available.
Error: Nothing to do
It's a fresh installed CentOS 6.5 and I've never edited CentOS yum repository information. What's wrong with gnuradio? They've removed the package from yum repository?
In their website, they provide several ways to install it including PyBOMBS. But I prefer yum. Building from source is somewhat bothering me so it's the last thing I will try.
By default CentOS does not include all the repositories needed by gnuradio and its dependencies.
You additionally need to configure/add at least RPMForge and Epel for your CentOS.
