Yum

'Yum is a package manager used to manage RPM packages. It's used in pretty much all Linux distros based around the [[RPM] package format, and is especially notable for being used in Red Hat distributions as well as in Fedora.

Name

Yum means Yellowdog updater, modified. There used to be a yup tool, which stood for yellowdog updater. Yum is a complete rewrite of yup.

Usage

Like most package managers, yum is quite simple to use. It requires root privileges in order to install and remove packages.

Installing packages

To install a package, issue:

# yum install <package>

Uninstalling packages

Updates

Yum supports updating individual packages or the entire system at once.

Sometimes, yum will fail to resolve dependencies for various reasons. You can use the --skip-broken option to skip packages whose dependencies could not be resolved:

You can search the remote repository for a package:
