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/*

How guys, can you help me I have problem with install centreon:
#yum install centreon-base-config-centreon-engine centreon
output

Trying other mirror.
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/

You can turn off File -> Preferences -> Settings, search for property http.proxyStrictSSL and turn it off.
Close visual studio and open again, it worked for me.
I faced this problem today when VSCode was running from WSL2 with Ubuntu 20-04 distro. Not your case exactly, but could be useful to others.
In my case the root cause is that our corporate network requires two custom CA certificates from ZScaler. You can easily verify whether your case is similar - google for the exact procedure, it is not complicated.
Anyway, I saved the certificates in a pem file and then followed the instructions on https://ubuntu.com/server/docs/security-trust-store to install them:
$ sudo apt-get install -y ca-certificates
$ sudo cp local-ca.crt /usr/local/share/ca-certificates
$ sudo update-ca-certificates
After that I closed and reopened VS Code and the SQL tools service installed just fine.
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
I am attempting to install Fedora 21 with additional packages (dhcp, tftp-server, tftp, subversion, vim) using cobbler as my provisioning system over pxeboot.
The problem is that the installation will show an error about packages/groups not existing when it tries to install packages for Fedora, specifically it will pop up an error for all of the packages I try to install in the list below. It seems that the repo information is not right because not a single one of my packages is being installed even though when I check the repo on the web they are present.Here are the relevant sections from my kickstart file.
install
url --url=http://192.168.1.1/cblr/links/Fedora_21_Server-i386/
repo --name="Fedora_21_i386_Server" --baseurl=http://192.168.1.1/cblr/repo_mirror/Fedora_21_i386/

part / --fstype="ext3" --grow --size=1
%packages
#base
#base-x
#editors
#graphical-internet
#system-tools
#admin-tools
#fonts
#lxde-desktop
dhcp
tftp
tftp-server
subversion
vim-enhanced
vsftpd
minicom
%end
I have also tried setting --baseurl as a Fedora mirror (--baseurl=http://mirror.pnl.gov/fedora/linux/releases/21/Server/i386/os/) but that does not work either. I have the above repo added as a cobbler repo and I have linked my Fedora 21 profile to it. One caveat is that I chose "No" for the local mirror option because right now my VM does not have enough space for the Fedora repo.
One solution is to install the packages in a post-install section using standard yum commands. For example,
%post
yum -y install minicom
yum -y install vsftpd
I've used this workaround with F20 installs.
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

* extras: centos.mirror.cdnetworks.com
* updates: 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.
