You can reinstall a package on a system running CentOS or RHEL using the dnf command. The dnf command is a package manager for RPM-based Linux distributions, such as CentOS and RHEL.
Here’s an example of how to reinstall a package using the dnf command:
sudo dnf reinstall package_name
This command will reinstall the package named “package_name”.
You can also use the --allowerasing option to allow the package to be reinstalled even if it will cause other packages to be removed.
sudo dnf reinstall --allowerasing package_name
You can also use the -y option to automatically answer yes to any prompts.
sudo dnf reinstall -y package_name
Please note that reinstalling a package will overwrite any existing configuration files and data, it’s always a good idea to backup your important data before reinstalling the package.
It’s always a good idea to check the dnf website for the latest version and other options.
