Installing Packages Using RPM and DPKG

When working with Linux distributions that use RPM (Red Hat Package Manager) or DPKG (Debian Package) systems, manual installation of packages is a common method, especially when packages are not available in standard repositories.

RPM is predominantly used in Red Hat-based distributions such as Fedora, CentOS, and RHEL. The command-line tool `rpm` handles package installation, removal, and querying. To install a package using rpm, you typically use:

“`bash
sudo rpm -i package-name.rpm
“`

The `-i` flag stands for install. However, rpm does not resolve dependencies automatically, so if the package requires other packages, you need to install those first or use a higher-level package manager like `yum` or `dnf`.

On Debian-based systems, the equivalent low-level tool is `dpkg`. The command to install a `.deb` package is:

“`bash
sudo dpkg -i package-name.deb
“`

Similar to rpm, `dpkg` does not handle dependencies on its own. If dependencies are missing, the installation will fail, and you will need to run:

“`bash
sudo apt-get install -f
“`

to fix broken dependencies and complete the installation.

Using Higher-Level Package Managers: YUM, DNF, and APT

Higher-level package managers build upon rpm and dpkg to offer automatic dependency resolution and more user-friendly commands.

  • YUM (Yellowdog Updater Modified): Used primarily in older Red Hat-based distributions such as CentOS 7. It fetches packages from configured repositories, resolves dependencies, and installs them.
  • DNF (Dandified Yum): The successor to YUM, now default in Fedora and newer Red Hat-based systems, offering improved performance and better dependency management.
  • APT (Advanced Package Tool): The primary package manager for Debian, Ubuntu, and their derivatives, which uses `dpkg` underneath but manages dependencies automatically.

To install a package using these tools, the commands are straightforward:

“`bash
sudo yum install package-name For YUM
sudo dnf install package-name For DNF
sudo apt-get install package-name For APT
“`

These package managers will download the package from repositories, resolve and install dependencies, and configure the software.

Installing Packages from Source

Sometimes, software may not be available in precompiled package formats, or you may want a specific version not offered by your distribution. In such cases, installing from source code is an option.

The general steps for installing software from source are:

  • Download the source code archive (commonly `.tar.gz` or `.tar.bz2`).
  • Extract the archive using `tar`:

“`bash
tar -xzf package-name.tar.gz
“`

  • Change into the extracted directory:

“`bash
cd package-name
“`

  • Prepare the build environment using the `./configure` script. This script checks for dependencies and sets up makefiles:

“`bash
./configure
“`

  • Compile the source code with `make`:

“`bash
make
“`

  • Install the compiled software system-wide:

“`bash
sudo make install
“`

Installing from source requires development tools like GCC and make, and often additional libraries. It also bypasses the package management system, so updates and removals must be handled manually.

Comparison of Package Installation Methods

Different package installation methods serve various needs and environments. Below is a comparison table highlighting key characteristics:

Method Dependency Handling Ease of Use Flexibility Typical Use Case
RPM / DPKG Manual Moderate Low Installing downloaded package files
YUM / DNF / APT Automatic High Moderate Standard package management via repositories
Source Compilation Manual Low High Custom builds, latest versions, unsupported packages

Understanding Package Managers on Linux

Linux distributions rely on package managers to install, update, and manage software packages efficiently. These tools automate the process of resolving dependencies, downloading the necessary files, and configuring software for your system. Familiarity with your distribution’s package manager is essential for seamless package installation.

Common package managers include:

Distribution Family Package Manager Package Format Basic Install Command
Debian, Ubuntu, Mint APT (Advanced Package Tool) .deb sudo apt install package-name
Fedora, Red Hat, CentOS DNF (or YUM for older versions) .rpm sudo dnf install package-name
Arch Linux, Manjaro Pacman .pkg.tar.zst sudo pacman -S package-name
SUSE Linux Zypper .rpm sudo zypper install package-name

Installing Packages Using APT on Debian-Based Systems

APT is the default package manager for Debian-based distributions and is widely used due to its ease of use and extensive repositories.

To install a package using APT:

  • Update the package index to ensure you have the latest information: 
    sudo apt update
  • Install the desired package: 
    sudo apt install package-name

Additional tips when using APT:

  • sudo apt upgrade updates all installed packages to their latest versions.
  • Use apt-cache search keyword to find packages related to a keyword.
  • To remove a package but keep configuration files, use sudo apt remove package-name.
  • To completely purge a package and its configuration files, use sudo apt purge package-name.

Installing Packages Using DNF or YUM on Red Hat-Based Systems

For Red Hat, Fedora, and CentOS, DNF is the modern package manager replacing YUM, though both are still in use on various versions.

Basic installation with DNF:

  • Update the repository metadata: 
    sudo dnf check-update
  • Install the package: 
    sudo dnf install package-name

For older systems still using YUM:

  • Update repository metadata: 
    sudo yum check-update
  • Install the package: 
    sudo yum install package-name

Additional commands:

  • To remove a package: sudo dnf remove package-name or sudo yum remove package-name.
  • To list installed packages: dnf list installed or yum list installed.
  • Use dnf search keyword or yum search keyword to find packages.

Installing Packages Using Pacman on Arch Linux

Pacman is the package manager for Arch Linux and its derivatives, known for its simplicity and speed.

To install a package:

  • Synchronize package databases and update system packages: 
    sudo pacman -Syu
  • Install the desired package: 
    sudo pacman -S package-name

Additional useful commands:

  • Remove a package but keep dependencies: 
    sudo pacman -R package-name
  • Remove package and dependencies not required by other packages: 
    sudo pacman -Rs package-name
  • Search for packages: 
    pacman -Ss keyword
  • List installed packages: 
    pacman -Q

Installing Packages From Source or Third-Party Repositories

Not all software is available in your distribution’s default repositories. In such cases, alternative installation methods include:

  • Building from Source:
    • Download the source code archive (e.g., .tar.gz or .tar.bz2).
    • Extract the archive: 
      tar -xf archive-name.tar.gz
    • Navigate into the extracted directory and follow typical build steps: 
      ./configure
make
sudo make install
