Debian review 2026
Debian · Volunteer upstream base
Debian ranks #6 of 16 enterprise Linux distributions in the Enterprise Linux Ledger 2026, with a Ledger Index of 61.4 out of 100. Debian gives five free years per release and the widest architecture list, with no vendor, no live patching and no release dates to plan around.

What the Ledger says
Debian is the base layer of this group: Ubuntu, Proxmox VE and most cloud images start from it, and it carries more architectures than any vendor. The scores are held back by what a volunteer project does not do: no live patching, no certifications, no management product, no release dates and five years of free updates against ten to fifteen from the commercial lines. What it has instead is a lock-in score near zero and a lifecycle that has kept its promises since 2015. The thing to check is the LTS years: the last two of the five are handled by a smaller sponsored team with fewer architectures, and anything past five years is a quote from Freexian.
Debian packages the GPU drivers and, since 13, ROCm, and leaves everything above that to the user. It has no AI platform, no assistant and no agent interface, and in 2026 it voted rules for contributors rather than features for users.
Capability by area
Buying, lock-in and release record
Buying and licence (commercial risk)(lower is better)
- Maintainer concentration1.5
- Over a thousand developers with no single employer; LTS work is done by a smaller paid group
- Backer health1.5
- No owner company; LTS depends on sponsor funding (the wiki asks companies that benefit to contribute)
- Licence-change risk0
- Debian Free Software Guidelines and the Social Contract; thousands of copyright holders
- Abandonment signs0.5
- Releases since 1993; 13.7 on 2026-09-12; the 2026 leader election had a single candidate
- Security response1.5
- Security team advisories with CVE references; LTS years rely on volunteers and sponsors; no published response-time targets
Technical lock-in(lower is better)
- Formats0.5
- deb, qcow2 and OCI; plain-text configuration
- Export path0.5
- Ubuntu and other derivatives take the same packages; nothing to convert
- Stack coupling0
- Any storage, any network, any tooling
- Hardware / cloud coupling0.5
- Any hardware; no official Google Cloud or Oracle Cloud images
- Skills and tooling coupling0.5
- The most common package tooling
Release credibility
- Cadence3
- A stable release about every two years (2023-06-10, 2025-08-09) with no dates announced in advance; point releases every two months
- Roadmap transparency4.5
- Everything is public: bug tracker, release team pages, votes, security tracker; there is no dated roadmap
- Say-do4
- Debian announces little and ships what it freezes; the 2025 AI resolution was withdrawn and replaced in 2026
- Velocity3
- Each release refreshes the base and adds one or two platform changes (firmware in 12, riscv64 and systemd-boot in 13)
- Lifecycle stability4.5
- Five-year windows kept since 8; in-place apt upgrades; Extended LTS to ten years
Partners and services
- Partner programme openness2
- No vendor; support is sold by third parties such as Freexian
- Multi-tenancy and self-service0.5
- No management product
- API and infrastructure-as-code3
- cloud-init, Ansible, Terraform and FAI-built images work unchanged
- Skills and certification2
- Large skills pool; no vendor certification (LPIC covers it generically)
