Fedora vs Ubuntu: release cycles, dnf vs apt, SELinux and servers

Short answer: pick Ubuntu for servers and first-time Linux users: an Ubuntu LTS release gets 5 years of standard security updates, while each Fedora release is maintained for about 13 months. Pick Fedora for a desktop or developer workstation when you want the newest kernel, GNOME and toolchains, SELinux by default and an early look at future RHEL releases.

Release numbers and support dates below are as of October 2026, taken from the Fedora Project’s release life cycle documentation and Canonical’s Ubuntu release cycle page. Nothing here was run on a Fedora or Ubuntu machine for this article; the commands come from each project’s own documentation and man pages.

Fedora vs Ubuntu at a glance

Release cadence and support: the difference that decides servers

Fedora ships a new version roughly every six months and keeps each one updated until four weeks after the release two versions later. Fedora’s own documentation calls that “approximately 13 months”; the exact end date moves with the date the later release actually ships. So Fedora 43 stops getting updates four weeks after Fedora 45 is out, and Fedora 44 four weeks after Fedora 46. There is no long-term support release. Every Fedora machine needs a major upgrade at least once a year:

sudo dnf --refresh upgrade
sudo dnf system-upgrade download --releasever=45
sudo dnf system-upgrade reboot

Ubuntu has two tracks. Interim releases (25.10, for example) also come every six months but get only 9 months of updates. LTS releases come every two years and get 5 years of standard security maintenance; Ubuntu Pro extends that to 10 years for both the main and universe repositories, and the Legacy add-on to 15. Canonical’s Pro page states it is free for personal use on up to 5 machines. An LTS server can therefore run for years between major upgrades, and when one is due, sudo do-release-upgrade moves it to the next LTS (upgrading Ubuntu covers the backup and the steps).

That single difference is why the rest of this comparison matters much more on a laptop than on a server. A box you want to leave alone for three years has no place on a release that expires in 13 months.

dnf vs apt: package management side by side

Both package managers resolve dependencies, verify signatures and do the same everyday jobs. The differences are in the details: dnf refreshes repository metadata on its own when the cache expires, while apt wants an explicit apt update first. dnf has long kept a transaction history you can undo; APT gained the same with apt history-list and apt history-undo in APT 3.2, which Ubuntu 26.04 ships, while Ubuntu 24.04 only logs to /var/log/apt/history.log.

Package names differ more than the commands do: Apache is httpd on Fedora and apache2 on Ubuntu, development headers end in -devel on Fedora and -dev on Ubuntu. The full command map, including yum and the Rocky Linux side, is in yum: command not found.

Where extra software comes from differs as well. Fedora’s repositories carry only free and open-source software, so media codecs and NVIDIA’s driver usually come from the third-party RPM Fusion repositories, and newer builds of single apps from COPR. Ubuntu splits its archive into main, universe, restricted and multiverse, installs NVIDIA’s driver from its own archive with ubuntu-drivers, and has PPAs on Launchpad for everything else. Treat COPR and PPAs alike: convenient, but maintained by whoever uploaded them.

Flatpak vs Snap

Both distributions add a sandboxed app format on top of their native packages, and they chose different ones. Ubuntu ships Canonical’s Snap: snapd runs as a service, Firefox, Thunderbird and the App Center itself are snaps on current releases, and snaps refresh themselves in the background unless you hold them with snap refresh --hold. Fedora ships Flatpak with Fedora’s own Flatpak remote, keeps Firefox as a normal RPM, and offers Flathub through GNOME Software once you enable third-party repositories.

On a desktop this decides how most graphical apps arrive and update. On a headless server it barely matters: server software installs through dnf or apt either way, and snap list shows you whatever Ubuntu did install as a snap.

SELinux vs AppArmor

Fedora runs SELinux in enforcing mode with the targeted policy: every file and process carries a label, and a service can touch only what its label allows. Ubuntu uses AppArmor, which confines individual programs with path-based profiles and leaves programs without a profile alone. SELinux is stricter and catches more; it is also the reason a setup that works on Ubuntu can fail on Fedora with a plain Permission denied although the file permissions look right.

A typical SELinux surprise, and the right fix

nginx as a reverse proxy in front of an app on port 8080 works on Ubuntu out of the box. On Fedora the same config answers with a 502 Bad Gateway, and the nginx error log shows connect() to 127.0.0.1:8080 failed (13: Permission denied) while connecting to upstream. The policy forbids the web server from opening network connections until you switch on a boolean:

getenforce                                   # Enforcing
sudo ausearch -m avc -ts recent              # shows the denied action
sudo setsebool -P httpd_can_network_connect 1

# web content outside /var/www needs the right label as well
# (semanage is in the policycoreutils-python-utils package)
sudo semanage fcontext -a -t httpd_sys_content_t "/srv/www(/.*)?"
sudo restorecon -Rv /srv/www

Resist setenforce 0: it switches protection off for the whole machine to fix one rule. On Ubuntu, sudo aa-status lists the loaded AppArmor profiles and which ones are enforcing. The same labelling rules apply on Rocky Linux and AlmaLinux, so anything you learn about SELinux on Fedora carries straight over to the RHEL family.

GNOME on both, configured differently

Fedora Workstation ships GNOME very close to how the GNOME project releases it, and each Fedora release brings the newest GNOME version. KDE Plasma Desktop is a full Fedora edition alongside it. Ubuntu also defaults to GNOME, but adds its own dock, the Yaru theme and desktop icons, and an LTS release keeps the same GNOME version for its whole life. If you prefer KDE, Xfce or another desktop on Ubuntu, the official flavours (Kubuntu, Xubuntu and others) ship it preconfigured. Both run Wayland sessions by default.

Fedora Workstation also uses Btrfs as its default file system, which makes snapshots and transparent compression easy. Ubuntu Desktop installs to ext4 by default. Neither choice matters much until you want snapshots before an upgrade.

Fedora Server vs Ubuntu Server

Both have a dedicated server edition. Fedora Server installs with Anaconda, puts the root file system on XFS inside LVM, leaves the rest of the volume group free for you to allocate, turns on firewalld and enables the Cockpit web console (port 9090) for remote administration. Ubuntu Server installs with Subiquity, sets up ext4 on LVM in its guided mode, includes cloud-init so the same image configures itself on any cloud, and leaves the ufw firewall installed but switched off until you enable it.

Technically Fedora Server is a capable, modern system. The catch is the calendar, not the software: a Fedora Server needs the major upgrade above every year, and each one can bring a new kernel, new major versions of languages and databases, and new defaults. That is fine for a lab or a box you rebuild often. For a production server the usual choice in the Red Hat family is a RHEL rebuild with a 10-year life instead.

Fedora or Ubuntu on a VPS?

For a VPS, the answer is nearly always Ubuntu LTS or Debian, or Rocky Linux if you want the Red Hat family. Fedora is rarely the right base for a server you rent by the month: the 13-month cycle forces yearly major upgrades on a machine you want to keep stable, and many providers do not offer a Fedora template at all. VMHeaven’s Linux VPS templates, for example, are Ubuntu, Debian, Rocky Linux and CentOS Stream; Fedora is not one of them. If your choice is really between Ubuntu and Debian, Debian vs Ubuntu covers that one.

• You like Fedora on your laptop and want the same habits on the server? Rocky Linux or AlmaLinux. They use the same dnf, SELinux, firewalld and RPM packaging, and what Fedora ships today reaches RHEL and its rebuilds a few years later. Rocky Linux 9 is on our template list, with security updates to 2032.
• You follow tutorials, use Docker images or want the biggest pool of answers? Ubuntu 24.04 LTS. Most guides and vendor repositories assume it.
• You need to test against Fedora’s newer packages? Run the official Fedora container image on any host instead of making the whole server Fedora: docker run --rm -it fedora:latest bash.

How do I tell which one a machine runs?

/etc/os-release exists on both and names the distribution and release:

grep -E '^(ID|VERSION_ID)=' /etc/os-release

# Fedora 44 prints:
ID=fedora
VERSION_ID=44

# Ubuntu 24.04 prints:
ID=ubuntu
VERSION_ID="24.04"

Checking the Linux version covers hostnamectl, the kernel version and how to see whether a release is still supported.

How to choose

• A server you want to leave alone for years: Ubuntu LTS (or Debian, or Rocky Linux). Not Fedora.
• First Linux desktop, or a machine for someone else: Ubuntu LTS. More answers online, longer between upgrades, drivers from its own archive.
• Developer workstation that should feel current: Fedora. New compilers, kernels and GNOME every six months, and SELinux habits that transfer to RHEL-family servers.
• You dislike Snap: Fedora, or an Ubuntu-based distribution that blocks it, such as Linux Mint.
• Your team or your tooling already standardised on one: stay with it. The cost of switching outweighs the differences in this table.
