2025 and 2026 brought a fresh wave of server operating systems. Ubuntu 26.04 LTS, Debian 13 (Trixie), AlmaLinux 10 and Rocky Linux 10 are all shipping now. So which one belongs on your next VPS? Here is a straight answer, with no marketing fluff.
Ubuntu 26.04 LTS, the safe all-rounder
Released in April 2026 and supported until 2031, Ubuntu 26.04 has the widest package ecosystem and the most tutorials online. If you want the path of least resistance for web apps, Docker, or a Node, Python or PHP stack, start here.
Debian 13 (Trixie), rock solid and lean
Debian values stability over novelty. Trixie is a great pick when you want a minimal, predictable base that simply keeps running. It has been a favourite for long-lived servers and self hosting for years.
AlmaLinux 10 and Rocky Linux 10, enterprise and RHEL compatible
Both are free, community-built rebuilds that are fully binary compatible with Red Hat Enterprise Linux 10. Reach for them when you run enterprise software, a control panel like cPanel, or anything that officially targets RHEL, all without a subscription fee.
Quick decision guide
- New to Linux, or general web hosting: Ubuntu 26.04 LTS
- Maximum stability, minimal footprint: Debian 13
- Enterprise or RHEL-targeted software, or cPanel: AlmaLinux 10 or Rocky Linux 10
First boot hardening for any distro
Whatever you pick, run these steps before you expose the server. On Debian or Ubuntu:
# update everything sudo apt update && sudo apt full-upgrade -y # firewall: allow SSH and web only sudo apt install -y ufw sudo ufw allow OpenSSH sudo ufw allow 80,443/tcp sudo ufw enable # turn off password and root SSH login (use keys instead) sudo sed -i 's/^#\?PermitRootLogin.*/PermitRootLogin no/' /etc/ssh/sshd_config sudo sed -i 's/^#\?PasswordAuthentication.*/PasswordAuthentication no/' /etc/ssh/sshd_config sudo systemctl restart ssh
On AlmaLinux or Rocky the same idea uses dnf and firewalld:
sudo dnf upgrade -y sudo systemctl enable --now firewalld sudo firewall-cmd --permanent --add-service=https --add-service=http sudo firewall-cmd --reload
All four are available at checkout, so you can match the OS to the job instead of the other way around.
