Linux Distribution Guide: Ubuntu, Debian, AlmaLinux

One of the first choices you face when ordering a VPS is the operating system. Ubuntu, Debian, or AlmaLinux? Each distribution has its own strengths, weaknesses, and ideal use cases. This guide helps you choose the distribution that best fits your needs.

Why Does Distribution Choice Matter?

Your Linux distribution choice affects:

• Package manager and software ecosystem: apt vs dnf
• Update cycle: Frequent updates vs long-term support
• Community and documentation: Ease of problem-solving
• Enterprise support: Commercial support options
• Security updates: How quickly patches arrive

Major Distribution Comparison

Ubuntu LTS: Best Choice for Getting Started

Ubuntu is the most widely used Linux distribution worldwide. Ubuntu LTS (Long Term Support) releases are particularly ideal for server environments.

Pros

• Large community: Easy to find solutions for any problem
• Up-to-date software: New versions arrive quickly
• Snap and PPA support: Additional software sources
• Cloud-init integration: Fast setup in cloud environments
• Docker and Kubernetes: Excellent container support
• Comprehensive documentation: Resources in many languages

Cons

• Snap packages are controversial (some users dislike them)
• Can be less stable than Debian
• Canonical's commercial decisions sometimes conflict with the community

Who Is It For?

# Ubuntu 24.04 LTS post-install basic check
lsb_release -a
# Ubuntu 24.04.x LTS

# Package manager
apt update && apt upgrade -y

# Popular software installs easily
apt install nginx docker.io python3-pip nodejs npm -y

Ubuntu is ideal for:

• Linux beginners
• Web application developers
• Docker/Kubernetes users
• Node.js, Python, Ruby developers
• Rapid prototyping

Debian: The Symbol of Stability

Debian is the parent distribution that Ubuntu is based on. Known for its "universal operating system" slogan, it stands out for its stability.

Pros

• Exceptional stability: Packages go through extensive testing
• Minimal installation: No unnecessary software
• Long-lived: Servers run for years without issues
• Security-focused: Security patches arrive quickly
• Free software philosophy: Completely open source

Cons

• Software versions are older than Ubuntu
• Less user-friendly (for beginners)
• Slow update cycle (major release every 2 years)

Who Is It For?

# Debian 12 (Bookworm) basic info
cat /etc/debian_version
# 12.x

# Newer software via backports
echo "deb http://deb.debian.org/debian bookworm-backports main" >> /etc/apt/sources.list
apt update
apt install -t bookworm-backports nginx

Debian is ideal for:

• Those who prioritize stability over performance
• Long-term server operators
• Those wanting minimal resource usage
• Experienced Linux administrators
• Database servers

AlmaLinux and Rocky Linux: Enterprise Class

These Red Hat Enterprise Linux (RHEL)-compatible distributions are designed for enterprise environments. They emerged to replace CentOS.

AlmaLinux vs Rocky Linux Difference

Pros

• 10-year support: Long-term security updates
• RHEL compatibility: Enterprise software works seamlessly
• SELinux: Advanced security policies
• Enterprise ecosystem: Compatible with cPanel, Plesk, etc.
• Free RHEL alternative: RHEL experience without commercial support

Cons

• Fewer community resources (compared to Ubuntu)
• Software versions are older
• dnf/rpm ecosystem less widespread than apt

Who Is It For?

# AlmaLinux 9 basic info
cat /etc/almalinux-release
# AlmaLinux release 9.x

# Package manager
dnf update -y

# EPEL repository (for additional software)
dnf install epel-release -y
dnf install htop fail2ban -y

# SELinux status
getenforce
# Enforcing (active)

AlmaLinux/Rocky is ideal for:

• cPanel/WHM users
• Running enterprise applications
• Environments requiring RHEL certification
• Those wanting long-term support
• PHP/MySQL-based web hosting

Recommendation Table by Use Case

Which Version Should I Choose?

For Ubuntu

# Always prefer LTS releases
# 2024: Ubuntu 24.04 LTS (Noble Numbat)
# 2026: Ubuntu 26.04 LTS (upcoming)

# Non-LTS releases (like 23.10) only get 9 months of support
# NEVER use non-LTS releases for servers

For Debian

# Use the Stable release (currently: Debian 12 Bookworm)
# Do not use Testing or Unstable on servers

# Version check
cat /etc/debian_version

For AlmaLinux/Rocky

# Use the latest major release (currently: 9.x)
# 8.x can also be used for RHEL 8 compatibility

# Version check
cat /etc/almalinux-release
# or
cat /etc/rocky-release

Changing Distributions

Switching from one distribution to another generally requires a reinstall. You can reinstall the OS from the REXE panel:

1. Back up your important data
2. Select your server in the REXE panel
3. Use the "Reinstall OS" option
4. Select the new distribution
5. Apply the new configuration after installation completes

Conclusion

If you're new to Linux, start with Ubuntu 24.04 LTS — it has the largest community support and documentation. If stability is your priority, choose Debian 12; for enterprise environments or cPanel, choose AlmaLinux 9. All three distributions perform excellently on REXE infrastructure.
