Hi! This post will make you familiar with the YUM utility provided with Fedora. You can easily download, install or remove any package/module after going through this easy YUM guide. Taking you directly to the commands, If you want to search for a module:

yum search <module name>

To get information about a module:

yum info <module name>

To install a module:

sudo yum install <module name>

To remove a module:

sudo yum remove <module name>

To check for updates:

yum check update

To install updates;

sudo yum update

To update a single module:

yum update <module name>

excluding a module from being updated:

yum --exclude=package <module name> updated

To find out the dependencies of a module

yum deplist <module name>

To uninstall a module:

yum remove <module name>
or
yum erase <module name>

To search for a module which can be directly installed using YUM

yum list | grep <module name>

To find whether a module has been installed or not:

yum list installed | grep <module name>

If in the output you see the package listed then it is installed else there will be no output.

To install a yum group. Say I want to install the group of editors

yum groupinstall editors

yum groupremove editors

To update a yum group:

yum groupupdate <group name>

To know the kernel-images currently installed:

rpm -q kernel

To remove old kernels:

sudo yum remove kernel

Fedora retains the three latest kernels to ensure that there is always a working kernel installed, in case the latest kernel breaks something. The limit can be changed by changing the value of ‘installonly_limit’ in the ‘/etc/yum.conf’ file.

To remove a specific kernel:

sudo yum remove <kernel package>
