In recent years, governments across the globe have been increasingly adopting Linux-based operating systems in place of proprietary platforms like Microsoft Windows. From cost savings and improved security to digital sovereignty and vendor independence, the motivations are varied—but the trend is clear: open source is gaining serious ground in the public sector.
Major Ongoing and Recent Government Linux Migrations

Germany – Schleswig-Holstein
In April 2024, the German state of Schleswig-Holstein announced a full migration of over 30,000 government workers from Windows to Linux. The switch includes LibreOffice, Nextcloud, Thunderbird, and other open-source tools, marking one of the largest Linux migrations in European government history.

Denmark – Ministry of Digital Affairs
Denmark’s Ministry of Digital Affairs has committed to a full transition to Linux and LibreOffice by autumn 2025. The first half of staff began migrating in June 2025, and the initiative aims to remove reliance on Microsoft software while embracing open-source solutions for long-term sustainability.

France – National Gendarmerie
The French National Gendarmerie began migrating to a custom Ubuntu-based OS (GendBuntu) back in 2008. By 2013, over 37,000 desktops had been converted. This migration resulted in substantial cost savings and reduced reliance on proprietary software.

India – Ministry of Defence
India recently deployed Maya OS, a secure Ubuntu-based system developed by the Defence Research and Development Organization (DRDO), to replace Windows on sensitive defence systems. The rollout is part of a broader push for self-reliance in critical digital infrastructure.

South Korea
South Korea announced plans to transition over 3.3 million government PCs to Linux following the end-of-life of Windows 7. The government has evaluated several Linux distros, including Harmonica OS and TmaxOS, as part of its move toward a more sovereign IT stack.
China, Russia, Turkey, and Brazil
Each of these countries has developed or deployed their own Linux distributions—such as China’s Kylin OS, Russia’s Astra Linux, Turkey’s Pardus, and Brazil’s government-sponsored Linux rollouts—for various public sector uses. Though typically limited to certain sectors, these deployments reflect a clear strategic direction.
Why Are Governments Switching?
- Cost Savings: Avoiding high licensing fees from Microsoft and other vendors.
- Digital Sovereignty: Retaining full control over software infrastructure and data.
- Security: Open-source systems allow for code audits, increased transparency, and better protection against backdoors.
- Support for Local Ecosystems: Investment in open-source fosters local tech development and reduces reliance on foreign vendors.
Challenges and Setbacks
Not all migrations have been seamless. Munich’s LiMux project—once hailed as a success—was reversed in 2017 due to user dissatisfaction and compatibility concerns. Still, many lessons from that experience are being applied in more recent transitions.
The Global Scope
- Confirmed large-scale migrations: Schleswig-Holstein (30,000+), French Gendarmerie (37,000+), South Korea (3.3 million planned), Denmark (Ministry-wide).
- Partial or sector-specific migrations: India’s Defense sector, Russian military and government, China’s strategic sectors, and educational institutions in Brazil and Turkey.
Final Thoughts
Governments around the world are reevaluating their software infrastructure in light of budget constraints, cybersecurity threats, and the need for greater technological autonomy. Linux offers a compelling alternative—one that is increasingly being embraced not just by tech enthusiasts, but by nations seeking long-term sustainability and control.
As 2025 continues, more public sector Linux migrations are expected to be announced. The age of open-source governance is no longer on the horizon—it’s here.
