The network unreachable message indicates that the computer is configured for IPv6 rather than IPv4 and the IPv6 location can’t be reached. Your network infrastructure or the network definition on the computer may need to be adjusted to support IPv6 or you’ll need to enable IPv4 networking on the computer.

I think that you need to solve the networking problem on that computer. I suspect that the following commands will all fail from that computer

$ curl https://pkg.jenkins.io/redhat-stable
$ curl http://pkg.jenkins.io/redhat-stable

Work with the people that provide your network connection to the public internet. They should be able to help you with the necessary settings to allow the operating system to download packages from the public internet.

How it can be network issues??

Because automated tests on the Jenkins infrastructure are successfully installing Jenkins 2.346.2 LTS on CentOS 7 and its derivatives.

I created a CentOS 7 machine and successfully installed Jenkins 2.346.2 just a few minutes ago.

We regularly test the rpm installation through several different paths, including:

It is possible that you have something very distinct in your environment that is not related to networking configuration. However, you’ve not found that distinct thing and we’ve seen many cases where corporate proxies or other network configurations caused failures that were specific to the network environment.
