Ubuntu Server 26.04 LTS just shipped with a quiet but vital shift. Installers now pull in HWE and OEM kernel packages by default. No more manual tweaks for tricky hardware. This matches desktop behavior long enjoyed by end users. Servers get the same out-of-box boost for Wi-Fi, GPUs, and niche peripherals. Canonical dropped this in Subiquity 26.04, the server installer baked into the live ISO. Subiquity release notes spell it out clearly.
Some machines require extra software (including drivers) to work correctly. This software is typically distributed automatically through a single .deb package called an OEM metapackage or HWE metapackage, which matches the hardware information. Previously, only Ubuntu Desktop installations would install such a package by default. Starting with Ubuntu 26.04, the package (if any) will also be installed for Ubuntu Server. That’s straight from the notes. Admins can flip it off via autoinstall: oem: install: false. Smart. Keeps control in expert hands.
And it’s timely. Ubuntu 26.04 LTS—Resolute Raccoon—landed April 23, powered by Linux 7.0. Five years of standard support to 2031. Ubuntu Pro stretches that to ten. Server pros eyeing datacenters will note the kernel’s fresh hardware enablement: Intel Panther Lake Xe3 graphics and NPU, EtherCAT for industrial nets, PREEMPT_RT real-time in the mainline archive. No more hunting low-latency kernels separately. Phoronix benchmarks confirm solid performance across AMD EPYC Turin and Strix Point.
But servers demand more than kernels. Subiquity 26.04 packs fixes too. User creation happens earlier, unlocking it for late-commands in automated setups. Crashes on VirtualBox unattended installs? Gone, per LP #2090834. Groups support lands in the identity section—override defaults or append sudo, adm cleanly. NVMe/TCP boot hangs fixed via LP #2127072. GeoIP timeouts that killed installs? Sorted. Invalid timezones or usernames no longer derail autoinstalls. Privacy tightens: no more logging network configs or user data in diagnostics, addressing CVE-2025-14551.
Zoom out to the full stack. Linux 7.0 anchors it all, with sched_ext eBPF scheduling for custom policies. PostgreSQL 18 triples I/O on reads for storage hogs, adds uuidv7 and OAuth. MySQL 8.4 LTS drops 32-bit cruft. Valkey 9.0 handles atomic slot migrations. PHP 8.5 brings pipe operators and array_first. Python 3.14, Rust 1.93, Golang 1.25, OpenJDK 25. ServeTheHome flags these for datacenter shifts. OpenSSH 10.2 goes post-quantum hybrid. Chrony defaults with NTS. Dracut replaces initramfs-tools.
Security layers thicken. Intel TDX host support for confidential VMs—memory encrypted, isolated. AppArmor profiles expand. Cargo-auditable audits Rust crates. A new HWE virt stack—qemu-hwe, libvirt-hwe—updates twice yearly, syncing with interim releases without rocking the LTS boat. Ubuntu release notes highlight this for stable virtualization upgrades. AMD SEV-SNP, NVIDIA MIG in QEMU. AMD64v3 baseline drops ancient x86.
Phoronix called the HWE/OEM move wise on X, echoing server admins’ wishes. Their post drew nods. It’s not flashy. But for deployments on Framework laptops or EPYC racks, it means fewer post-install apt installs. Fewer support tickets. Hardware that just works.
Tradeoffs exist. Rust coreutils at 0.7.0—pre-1.0—raised eyebrows on X from Geoff Langdale. Sudo-rs defaults, original sudo renamed. Some lament no Linux 7.1 NTFS driver yet. IBM Z bumps to z15 minimum. RISC-V sticks to RVA23.
Still, this cements Ubuntu Server’s datacenter grip. HWE/OEM auto-install seals the deal. Pair it with virt-hwe for clouds. Throw in TDX for secrets. Canonical’s betting big on LTS reliability. Deployments will follow.
