Ubuntu 25.10 (Questing Quokka) EOL July 2026 Options

Ubuntu 25.10 'Questing Quokka' Reaches End of Life July 1, 2026 — Compare Your Options

Canonical's Ubuntu 25.10 'Questing Quokka' will reach its end of life on July 1, 2026. With roughly nine months remaining, you have time to execute a deliberate migration or support strategy — but the clock is ticking. This is not an LTS release, so vendor support ends cleanly on that date with no overlapping extended support period.

Your infrastructure manager, procurement lead, or IT director should consider one of three realistic paths: upgrade to a supported release, purchase vendor extended support if available, or move to third-party maintenance. Each option carries a distinct cost profile, risk level, and timeline, and each suits different workload types.

Option 1: Migrate or Upgrade to a Supported Release

Best for: Environments under active development, virtual machines that can be rebuilt quickly, and teams that want to stay on current kernel and toolchain.

Upgrading from 25.10 to the next interim release (likely 26.04 LTS or 26.10) keeps you on a supported version with access to Canonical's repositories and security patches. The migration path is standard: do-release-upgrade or a fresh install.

Pros:

• No additional vendor cost for the OS itself
• You remain on a Canonical-supported branch
• Access to newer packages and kernel features

Cons:

• Requires careful testing and application compatibility validation
• May break custom configurations, proprietary drivers, or legacy dependencies
• Production downtime risk, unless you have a proper blue-green or rolling upgrade process
• Non-LTS releases can require more frequent migration

Cost profile: Internal engineering time only. Expect 8–40 hours per server for testing, staging, and cutover, depending on complexity.

Option 2: Vendor Extended Support (if offered)

Best for: Organizations that cannot migrate quickly but have a budget for annual vendor maintenance and want to keep the original OS line.

Canonical does offer Ubuntu Pro with extended security maintenance (ESM) for LTS releases. However, 25.10 is not an LTS release. ESM is typically available only for LTS versions. Check the vendor page on our site for current eligibility; in most cases, non-LTS releases receive no extended support from Canonical after the standard nine-month lifecycle.

If extended support were available, you would typically pay a per-node subscription fee and gain continued security patches for high and critical CVEs. The practical reality for 25.10 is that this path likely does not exist.

Pros:

• Familiar environment stays static
• Security patches continue without application re-testing

Cons:

• Annual license cost (often $25–$500/node/year depending on support tier)
• You remain on an aging OS branch that may lack modern kernel features
• Limited availability for non-LTS releases

Cost profile: Vendor subscription fee plus minimal internal effort. But check first — this option probably does not apply to Ubuntu 25.10.

Option 3: Third-Party Maintenance (Recommended for Stable Workloads)

Best for: Stable, non-development production systems that just need to keep running — for example, a legacy application server, internal database host, or embedded device that must operate without code changes.

Third-party support from 3rd Party Support keeps your Ubuntu 25.10 environment functioning safely past July 1, 2026. You receive backported security patches, bug fixes, and expert engineering support — without being forced to upgrade or pay annual vendor subscriptions.

Pros:

• No forced migration: your stack remains unchanged
• Cost-effective compared to vendor extended support (typically 40–60% less)
• Continued CVE remediation and break/fix support
• One contract covers your full hardware and software stack

Cons:

• You are not on Canonical's latest kernel or package tree
• New feature development stops — third-party support maintains, not enhances
• Requires trust in the third-party provider's response time and patch quality

Cost profile: Fixed annual or multi-year contract. No per-incident fees. Usually less expensive than vendor extended support.

Decision Checklist

Use this quick guide to match your workload profile to the best path:

Workload Type	Recommended Path	Why
Actively developed, DevOps pipeline, containers	Upgrade	You need latest tools and can tolerate rebuilds
Stable legacy app, no developer resources	Third-party support	Keep running without change; lowest total cost
Regulatory environment requiring vendor chain	Vendor extended support (if available)	Audit-driven need for original vendor name
Mixed fleet, phased migration over 12+ months	Third-party support on older nodes	Buy time to decommission or upgrade at your pace

Your Next Step

If your Ubuntu 25.10 systems need to keep running after July 1, 2026, and you prefer not to upgrade immediately, contact our team to discuss a third-party support contract. We can cover your entire enterprise hardware and software stack, including Ubuntu, RHEL, Windows Server, and legacy databases.

Nine months is enough time to execute any of these paths — but the sooner you decide, the smoother the transition. Review your server inventory, categorize workloads by stability and criticality, and choose the option that best fits your operational reality.
