Candidates should be able to perform package management using RPM, YUM, and Zypper.

Key Knowledge Areas

  • Install, re-install, upgrade and remove packages using RPM, YUM, and Zypper
  • Obtain information on RPM packages such as version, status, dependencies, integrity, and signatures Determine what files a package provides, as well as find which package a specific file comes from Awareness of dnf

The following is a partial list of the used files, terms, and utilities:

Terms and Utilities

  • rpm
  • rpm2cpio
  • /etc/yum.conf
  • /etc/yum.repos.d/
  • yum
  • zypper


RedHat Package Manager (RPM) and YellowDog Update Manager (YUM) are used by Fedora, RedHat, RHEL, CentOS, RocksOS, ... to manage packages. The package format is called RPM and can be managed by rpm tools but if you want to use the repositories to install, update, search, ... packages, or even upgrade the whole system, you can use the yum command. To have a deeper understanding of the repositories, please refer to the previous section (102.4); Here I assume that you know the concept.


yum is the package manager used by RedHat-based systems. Its configuration files are located at /etc/yum.conf and /etc/yum.repos.d/. Below is a sample.

# cat /etc/yum.conf

And here is a sample of an actual Repo file on a Fedora system:

# cat /etc/yum.repos.d/fedora.repo
name=Fedora $releasever - $basearch

name=Fedora $releasever - $basearch - Debug

name=Fedora $releasever - Source

We use yum like yum [OPTIONS] [COMMAND] [PACKAGE_NAME].

One of the most important options is -y which says yes to the Y/N questions.

And here you can find some of the commands:

Command Description
update Updates the repositories and update the names of packages, or all if nothing is named
install Install a package
reinstall Reinstall a package
list Show a list of packages
info Show information about a package
remove Removes an installed package
search Searches repositories for packages
provides Check which packages provide a specific file
upgrade Upgrades packages and removes the obsolete ones
localinstall Install from a local rpm file
localupdate Updates from a local rpm file
check-update Checks repositories for updates to the installed packages
deplist Shows dependencies of a package
groupinstall Install a group, say "KDE Plasma Workspaces"
history Show history of the usage

This is a sample installation:

# yum install bzr

You can also use the wildcards:

# yum update 'cal*'

Fun fact: Fedora Linux uses dnf as its package manager and will translate your yum commands to its dnf equivalents.


This tool will download rpms from repositories without installing them. If you need to download all the dependencies too, use the --resolve switch:

yumdownloader --resolve bzr


The rpm command can run ACTIONs on individual RPM files. You can use it like rpm ACTION [OPTION] rpm_file.rpm

One of common options is -v for verbose output and these are the common ACTIONs:

Short Form Long Form Description
-i --install Installs a package
-e --erase Removes a package
-U --upgrade Installs/Upgrades a package
-q --query Checks if the package is installed
-F --freshen Only update if it's already installed
-V --verify Check the integrity of the installation
-K --checksig Checks the integrity of an rpm package

Please note that each action might have its specific options.

Install and update

In most cases, we use -U which Installs or upgrades a package.

  • RPM does not have a database of automatic package installation, so it can not remove the automatically installed dependencies.

If you have an rpm with all of its dependencies, you can install them using rpm -Uvh *.rpm. This will tell rpm not to complain about the dependencies if it is presented in other files. Here the -h creates 50 hash signs to show the progress.

In some cases - if you know what you are doing - you can use --nodeps to prevent the dependency check or even use --force to force the install / upgrade despite all the issues & complains.


A normal query is like this:

[root@fedora tmp]# rpm -q breezy-3.2.1-3.fc36.x86_64.rpm
[root@fedora tmp]# rpm -q breezy
[root@fedora tmp]# rpm -q emacs
package emacs is not installed

And you can use these options to spice it up:

Short Long Description
-c --configfiles Show the packages configuration files
-i --info Detailed info about a pacakge
-a --all Show all Installed packages
--whatprovides Shows what packages provide this file
-l --list Query the list of files a package installs
-R --requires Show dependencies of a package
-f --file Query package owning file


You can verify your packages and see if they are installed correctly or not. You can use the -Vv option for verbose output or just use the -V to verify and see only the issues. This is the output after I edited the /bin/tmux manually:

[root@fedora tmp]# rpm -V tmux
S.5....T.    /usr/bin/tmux

And this is part of the man rpm's -V section:

    S Size differs
    M Mode differs (includes permissions and file type)
    5 digest (formerly MD5 sum) differs
    D Device major/minor number mismatch
    L readLink(2) path mismatch
    U User ownership differs
    G Group ownership differs
    T mTime differs
    P caPabilities differ

You can also check the integrity of an rpm package with -K:

# rpm -Kv breezy-3.2.1-3.fc36.x86_64.rpm
    Header V4 RSA/SHA256 Signature, key ID 38ab71f4: OK
    Header SHA256 digest: OK
    Header SHA1 digest: OK
    Payload SHA256 digest: OK
    V4 RSA/SHA256 Signature, key ID 38ab71f4: OK
    MD5 digest: OK

The above output shows that this file is valid.


[root@fedora tmp]# rpm -e tmux
error: Failed dependencies:
    tmux is needed by (installed) anaconda-install-env-deps-36.16.5-1.fc36.x86_64
  • rpm removes the package without asking!
  • rpm won't remove a package that is needed by another package

Extract RPM Files


The cpio is an archive format (Just like zip or rar or tar). You can use the rpm2cpio command to convert RPM files to cpio and then use the cpio tool to extract them:

[root@fedora tmp]# rpm2cpio breezy-3.2.1-3.fc36.x86_64.rpm > breezy.cpio
[root@fedora tmp]# cpio -idv < breezy.cpio


The SUSE Linux and its sibling openSUSE use ZYpp as their package manager engine. You can use YAST or Zypper tools to communicate with it.

These are the main commands used in zypper:

Command Description
help General help
install Installs a package
info Displays information of a package
list-updates Shows available updates
lr Shows repository information
packages List all available packages or packages from a specific repo
what-provides Show the owner of a file
refresh Refreshes the repositories information
remove Removes a package from the system
search Searches for a package
update Checks the repositories and updates the installed packages
verify Checks a package and its dependencies

You can shorten the command when using zypper, so zypper se tmux will search for tmux.

Other tools

YUM and RPM are the main package managers on Fedora, RHEL & Centos but other tools are also available. As mentioned, SUSE uses YaST, and some modern desktops (KDE & Gnome) use PackageKit which is a graphical tool. It is also good to note that the dnf suite is also gaining popularity and is pre-installed on Fedora systems.
