sudo yum makecache && sudo yum -y install ion
sudo dnf makecache && sudo dnf -y install ion
But if you are interested in the details with step-by-step instructions, the following information will be helpful.

First things first, you will need access to a server or computer running CentOS 8. This guide was written specifically with a server running CentOS 8 in mind, although it should also work on older, supported versions of the operating system.
Also, make sure you are running a regular, non-root user with sudo privileges configured on your server. When you have an account available, log in as your non-root user to begin.
There are several ways to install cgrfetch on CentOS 8. You can use (links are clickable):
In the following sections, we will describe each method in detail. You can choose one of them or refer to the recommended one.
First, update dnf packages database with
dnf by running the next command:
sudo dnf makecache --refresh
After updating database,
You can install cgrfetch using
dnf by running the
sudo dnf -y install ion
Because cgrfetch is available in CentOS 8’s default
it is possible to install it from these repositories using the
To begin, update local packages database with
yum using the following command.

When you run the
dnf update, all system packages with available updates are updated.

the argument to the dnf update command.
dnf update ion
To uninstall only the
cgrfetch package you can execute
sudo dnf remove ion
Interplanetary Overlay Network (ION) software distribution is an implementation of Delay-Tolerant Networking (DTN) architecture as described in Internet RFC 4838. This is a suite of communication protocol implementations designed to support mission operation communications across an end-to-end interplanetary network, which might include on-board (flight) subnets, in-situ planetary or lunar networks, proximity links, deep space links, and terrestrial internets. Included in the ION software distribution are the following packages: * ici (interplanetary communication infrastructure) a set of libraries that provide flight-software-compatible support for functions on which the other packages rely * bp (bundle protocol), an implementation of the Delay-Tolerant Networking (DTN) architecture's Bundle Protocol. * dgr (datagram retransmission), a UDP reliability system that implements congestion control and is designed for relatively high performance. * ltp (licklider transmission protocol), a DTN convergence layer for reliable transmission over links characterized by long or highly variable delay. * ams - an implementation of the CCSDS Asynchronous Message Service. * cfdp - a class-1 (Unacknowledged) implementation of the CCSDS File Delivery Protocol. This package contains the binary files.
