Hi Team,
Please note we have local repository configured.

[root@mpe3100 yum.repos.d]# cat /etc/yum.repos.d/hp.repo

The cache has been cleared

root@mpe3100 yum.repos.d]# rm -fr /var/cache/yum/*

Still we get the below error when we run yum install gcc

Please confirm if we need to download and install the last four packages listed in error

check dns resolver /etc/resolv.conf

solved the issue, was clear and to the point.

If you are using satelitte6 and have Content Views with custom channel names or different from the one used of the container base image (by default 7Server) remember to add the —releasever=xyz modifier to all your yum commands

RUN yum clean all && yum —releasever=7.3 update && \ yum repolist —disablerepo=* && \ yum-config-manager —disable * > /dev/null && \ yum-config-manager —releasever=7.3 —enable rhel-7-server-rpms && \ yum install —releasever=7.3 -y bzip2 fontconfig

Consider also this solution to the problem I had below. (to [Errno 14] but also encountered [Errno 256] with HTTPS Error 404 — Not Found. The Errno 14 is perhaps most likely due to URL and «releasever» setting while Errno 256 related to GPG.

https://access.redhat.com/solutions/2850911 — As GPG armor is not enabled on server side, so ensure repo_gpgcheck is set to 0 in yum.conf file for RHEL clients.

Fresh install of RHEL 7.4 on VirtualBox 5.2 and have the same issue, though this did not resolve it. Followed these instructions up to «Install the latest updates» https://developers.redhat.com/products/rhel/hello-world/#fndtn-virtualbox_get-ready-for-software-development

Following issue on «yum update» or «yum repolist» as root (though system already registered and attached to RedHat Subscription Manager)

How to solve Errno 256: httpd-2.4.6-97.el7.centos.x86_64: [Errno 256] No more mirrors to try

Have you been trying to work with apache and your computer won’t let you download anything related to apache because there are no more mirrors to try? then you are in the right place. Other guides can be found from these links: Setting-up-SElinux-on-a-Linux-server/ and how-to-create-and-deliver-a-report-on-system-utilization-on-a-Linux-based-os/ and how-to-create-a-static-pod-in-Kubernetes-with-demos-that-can-help-you-become-a-better-kubernetes-administrator/ and how-to-use-container-insights-to-get-the-full-benefits-of-azure-monitor-for-azure-Kubernetes-workload/. In this guide, I am going to be showing you the easiest way to fix this with just one simple command, but you might have to write some other two from our previous guide before this will work.

The above image simply implies that :

Errors were encountered while downloading packages.

Let’s run through two commands in the previous guide how-to-solve-cannot-find-a-valid-base-url-for-repo-base-7-x86_64/ before proceeding with this

Make sure that you are in the root shell when you run the commands above. The next step would be a yum update

yum clean all command removes the cache of repositories which are enabled in /etc/yum.repos.d/*.repo. Read what the manpages have to say about it below

# man yum . clean Clear out cached package data yum clean packages Delete packages saved in cache yum clean all Clean out all packages and meta data from cache

After running yum clean all command we are ready to run # yum install httpd again and this time around the download would not show Errno 256 as seen from the screenshot below

Summary

If you experience Errno 256 the one simple command that you can use to fix this on centos7 is #yum clean all but before that make sure you run #ONBOOT=no, #dhclient and #yum update. After these then if you run #yum install httpd you will not experience or see Errno 256 anymore.

I hope you found this blog post helpful. If you have any questions, please let me know in the comment session.
