To install chromium browser in fedora you need to add a repo file to the yum.repos.d dir as it is not available in rpm fusion repos. So download the repo file from the link below:
Right click on the fedora-chromium-stable.repo and save it to you hard drive by selecting “Save Link As”.
Now open terminal and cd to the location/dir where you downloaded the file. After that run this command:
sudo cp fedora-chromium-stable.repo /etc/yum.repos.d
And now time to install it:
sudo yum -y install chromium
And that’s it.
