France DINUM mandates government-wide Linux migration; 2.5 million civil servant workstations to exit Windows by 2030

France’s Interministerial Digital Directorate (DINUM) announced on 8 April 2026 that it will migrate its own workstations from Windows to Linux and has ordered every government ministry to submit a formal plan to eliminate extra-European digital dependencies by autumn 2026. The directive covers operating systems, collaboration tools, AI platforms, databases, virtualisation and network equipment. It follows a January 2026 mandate requiring 2.5 million civil servants to replace Microsoft Teams with the sovereign Visio platform by 2027. La Suite Numérique – a sovereign productivity stack including encrypted messaging app Tchap, deployed to 600,000 civil servants – is the designated desktop replacement. No specific Linux distribution has been named. France’s Gendarmerie Nationale has operated 100,000 Linux workstations since 2008. Similar moves are underway in Germany’s Schleswig-Holstein state and Austria’s armed forces.
