Intel ended support for Clear Linux OS in July 2025, effective immediately. The company no longer promises security patches, updates, or maintenance, and official project repositories have been archived or made read-only. If you still run Clear Linux, plan to migrate to a distribution with active maintenance rather than treating old installation media or repository copies as a supported update path.
What Intel’s shutdown means
The Clear Linux team announced in July 2025 that it was ending support for the operating system. Its statement said Intel would stop providing security patches, updates, and maintenance, and that the Clear Linux GitHub repository would be archived in read-only mode. The team advised current users to plan a move to an actively maintained Linux distribution.
This is an end of support, not just a pause in feature development. The official installer repository was archived on August 7, 2025, and its notice says Intel does not provide or guarantee maintenance, bug fixes, new releases, or updates; it also says Intel no longer accepts patches. The distribution and bundle repositories carry similar discontinuation notices. Existing source code, documentation, and release artifacts may still be accessible, but their availability does not mean the operating system or its update path is maintained.
Why Clear Linux was notable
Clear Linux was an open-source rolling-release distribution designed for performance and security from cloud to edge, with particular attention to Intel architecture. Its approach treated performance as a full-system effort rather than a single kernel setting: the project tuned its compiler toolchain, libraries, kernel, boot process, and power-management defaults.

Optimization across the software stack
Clear Linux documentation describes techniques including aggressive compiler flags, CPU-specific library builds, link-time optimization (LTO), profile-guided optimization (PGO), and a performance-oriented CPU governor. The documented optimization model identified Intel’s second-generation microarchitecture code-named Westmere, released in 2010, as its main minimum hardware generation. That describes the project’s stated model, not a guarantee that every Clear Linux release or feature required Westmere.
What its performance claims do—and do not—show
Clear Linux’s importance was partly methodological: it made Intel-focused, coordinated tuning across the toolchain and operating system visible to users. That history does not establish a universal speed advantage over Ubuntu or another distribution. Performance depends on the workload, hardware, drivers, software versions, and power behavior; a result on one setup would not by itself predict another user’s experience.
Can you still use Clear Linux safely?
An existing installation may continue to boot and run, but Intel no longer promises security fixes or updates. That leaves users without an assured path for receiving fixes for newly discovered vulnerabilities or other maintenance. For an internet-connected machine, a server, or a device holding sensitive data, continued use should not be treated as equivalent to running a supported distribution.
An archived ISO, a local package cache, or a mirror may let you reinstall or access old artifacts. None of those supplies ongoing security coverage from Intel. If you must keep a system running temporarily while preparing a migration, limit its exposure and avoid relying on it for workloads that require current security maintenance.

Intel recommends moving to an actively maintained distribution but does not prescribe a single successor. Choose based on the system’s role and your maintenance requirements, then inventory the installation before replacing it.
- Record what the system does. List services, applications, scheduled jobs, users, network settings, and any hardware-specific drivers or firmware dependencies.
- Preserve data and configuration. Back up application data and configuration files, and verify that the backups can be restored. Keep a copy of any boot settings or custom system configuration you will need to reproduce.
- Choose a maintained distribution against your requirements. Check its current security-update policy, support horizon, hardware and driver compatibility, package availability, release model, and installation and rollback options. Match the choice to the workload rather than selecting a replacement solely because it has a performance reputation.
- Test before switching critical systems. Where practical, install the candidate distribution on spare hardware or a separate disk. Validate required applications, drivers, services, and performance on the actual workload.
- Move the workload and verify it. Install the maintained system, restore data and settings selectively, and check that services start, devices work, and backups run before retiring the old installation.
| Selection factor | What to verify |
|---|---|
| Security updates and support horizon | How security fixes are delivered, which releases receive them, and how long the chosen release is supported. |
| Hardware and drivers | Whether the distribution supports the machine’s CPU, graphics, network devices, storage, and any vendor-specific drivers or firmware. |
| Packages and applications | Whether required software is available through maintained packages or another supported installation method. |
| Performance and power behavior | How the system behaves on the actual workload, including performance, thermals, and power use; defaults and tuning controls vary. |
| Release model | Whether the distribution’s update cadence and upgrade process fit the system’s availability and maintenance needs. |
| Installation and recovery | Whether installation, backups, rollback, and recovery methods are practical for the system’s role. |
Why did Intel end Clear Linux?
The shutdown announcement and repository notices establish that support ended, but they do not give a project-specific budget figure or a definitive internal business rationale. Without an explicit explanation from Intel, attributing the decision to a particular financial or corporate cause would be speculation.
