Ubuntu review 2026
Ubuntu Server with Ubuntu Pro · Calendar-driven builder
Ubuntu ranks #2 of 16 enterprise Linux distributions in the Enterprise Linux Ledger 2026, with a Ledger Index of 75.7 out of 100. Ubuntu keeps the most predictable calendar in the group and now ships CUDA and ROCm in its archive; the long tail of support is a paid subscription.

What the Ledger says
Ubuntu scores highest on the two things a planner feels first: a calendar that has held for twenty years and a support window that now runs to 15 years. The capability lines are strong rather than reference in most domains because the vendor tooling (Landscape, FIPS, STIG profiles) sits behind the Pro subscription and the on-premises Landscape price is high. Security is a 4 and not a 5 because FIPS 140-3 is certified for 22.04 only and 24.04 is still in assessment. The thing to check is the Pro budget: free covers five years, and years 6 to 15 cost USD 500 to 750 per machine per year at list.
Ubuntu's AI story is packaging: CUDA and ROCm in the archive and inference snaps that pick a backend for the hardware. There is no assistant for operators and no agent interface beyond the Landscape and MAAS APIs.
Capability by area
Buying, lock-in and release record

Technical lock-in(lower is better)
- Formats1
- deb, qcow2 and OCI; snaps depend on Canonical's proprietary Snap Store backend
- Export path0.5
- Debian-family packages and skills transfer; Pro features (Livepatch, ESM) do not
- Stack coupling0.5
- Landscape, MAAS, Juju and LXD are optional
- Hardware / cloud coupling0.5
- Any x86 or Arm server; Pro works offline with a token
- Skills and tooling coupling0.5
- The most common server Linux skills
Release credibility
- Cadence5
- April and October every year since 2004, an LTS every even April; 26.04 shipped 2026-04-23
- Roadmap transparency4
- Public release cycle page with dates to 2041, release notes on Discourse, Launchpad in the open; Pro plans only in blogs
- Say-do4
- CUDA and ROCm in the archive shipped with 26.04 as announced; inference snaps shipped; 24.04 FIPS 140-3 still in assessment two years after release
- Velocity4
- Each LTS carries several substantive changes (24.04: kernel 6.8, Netplan 1.0, TPM encryption preview; 26.04: kernel 7.0, CUDA and ROCm in the archive)
- Lifecycle stability4.5
- 5 plus 5 plus 5 years, dates kept to the month; the Legacy window is security patching only
Partners and services
- Partner programme openness4
- Open reseller and cloud partner programmes; terms not published
- Multi-tenancy and self-service3
- Landscape accounts and access groups; on-premises Landscape is priced per machine
- API and infrastructure-as-code4
- Landscape and MAAS APIs, Juju, cloud-init, Terraform providers
- Skills and certification3.5
- The largest skills pool; Canonical's own certification programme is small
