How to install Chromium browser on CentOS, RHEL or Fedora

Chromium is not the default web browser and is not even installed by default in CentOS, Red Hat, or Fedora. It's not even available in the distributions' default package repository.

You can still install Chromium web browser using dnf or yum, though you first need to enable the epel repository.

epel repository can be enabled by installing epel-release package using dnf or yum.

1. Launch terminal from the Dock or from the Applications overview search.
2. Install epel-release package using dnf.

   $ sudo dnf install --assumeyes epel-release
