## Government

As local governments come under pressure from institutions such as the World Trade Organization and the International Intellectual Property Alliance, some have turned to Linux and other free software as an affordable, legal alternative to both pirated software and expensive proprietary computer products from Microsoft, Apple and other commercial companies. The spread of Linux affords some leverage for these countries when companies from the developed world bid for government contracts (since a low-cost option exists), while furnishing an alternative path to development for countries like India and Pakistan that have many citizens skilled in computer applications but cannot afford technological investment at "First World" prices. Cost is not the only factor being considered, though – many government institutions (public and military) in North America and the European Union make the transition to Linux because of its superior stability and the openness of the source code, which strengthens information security.[2][3][4][5][6]

### Africa

* In 2004, Venezuela's government approved the 3390 decree,[41] to give preference to using free software in public administration. One result of this policy is the development of Canaima, a Debian-based Linux distribution.

### Europe

#### Austria

* In 2005, Austria's city of Vienna chose to start migrating its desktop PCs to Debian-based Wienux.[42] However, by 2011, the idea was largely abandoned, because the necessary software was incompatible with Linux.[43]

#### Czech Republic

* In 2005, Česká pošta (Czech Post) migrated 4,000 servers and 12,000 clients to Novell Linux.[44][45]

#### France

* In 2007, France's national police force (the National Gendarmerie) started moving their 90,000 desktops from Windows XP to a Ubuntu based OS, GendBuntu, over concerns about the additional training costs of moving to Windows Vista, and following the success of OpenOffice.org roll-outs.

* In 2003, The city government of Munich, Germany, choose to migrate its 14,000 desktops to Debian-based LiMux.[53] Even though more than 80 percent of workstations used OpenOffice and 100 percent used Firefox/Thunderbird five years later (November 2008),[54] an adoption rate of Linux of only 20 percent (June 2010) was achieved.[55] The effort was later reorganized, focusing on smaller deployments and winning over staff to the value of the program. By the end of 2011 the program had exceeded its goal and changed over 9000 desktops to Linux.[56] The city of Munich reported at the end of 2012 that the migration to Linux was highly successful and has already saved the city over €11 million (US$14 million).[57] Recently the Deputy Mayor Josef Schmid said that the city is putting together an independent expert group to look at moving back to Microsoft due to issues in LiMux, the primary issues have been of compatibility; users in the rest of Germany that use other (Microsoft) software have had trouble with the files generated by Munich's open-source applications. The second is price, with Schmid saying that the city now has the impression that "Linux is very expensive" due to custom programming, The independent group will advise the best course of action, and if that group recommends using Microsoft software, Schmid says that a switch back isn't impossible. The city council said they already saved more than US$10 million, and there is no major issue with the switch to Linux.[58] Some observers, such as Silviu Stahie of Softpedia have indicated that the attempted rejection of Linux has been influenced by Microsoft and its supporters, and that this is predominantly a political issue and not a technical one. Microsoft's German headquarters has committed to move to Munich as part of this issue.[59] In 2017, the Munich city council voted to transition back to Microsoft Windows 10,[60] citing compatibility issues with LiMux and the high cost of custom programming. By 2020, the city had begun the full migration of its workstations to Windows 10,[61] with plans to complete the transition by 2023. Critics argued that the decision was influenced by political pressures and lobbying rather than purely technical issues. Nonetheless, the transition continued, marking the end of Munich's ambitious open-source LiMux project. The cost of the switch was estimated to be over €30 million, despite earlier savings from using Linux.[56] A significant number of workstations in other government institutions, such as the Federal Employment Office of Germany (Bundesagentur für Arbeit), continue to use Linux, with 13,000 public workstations running openSUSE.[62]
* By 2009, the Federal Employment Office of Germany (Bundesagentur für Arbeit) has migrated 13,000 public workstations from Windows NT to openSUSE.[63]
* In 2024, State of Schleswig-Holstein in Germany plans to replace Windows with Linux and Libreoffice.[64]

* In 2014, Russia announced plans to move their Ministry of Health to Linux as a counter to sanctions over the annexation of Crimea by the Russian Federation and a means of hurting US corporate interests, such as Microsoft.[70]
* In 2018, Russia began adopting Astra Linux, an operating system which is certified to handle data classified as "special importance", on their military computer systems.[71]

#### Spain

* In 2003, Spain was noted as the furthest along the road to Linux adoption,[72] for example with Linux distribution LinEx
* In 2004, the regional Andalusian Autonomous Government of Andalucía in Spain developed its own Linux distribution, called Guadalinex.[73]
* In 2008, The city government of Barcelona in Spain announced that it would migrate all desktop software from proprietary to free/open-source alternatives, and would gradually migrate from proprietary operating systems to Linux.[74]

#### Switzerland

* In 2001, Switzerland's Canton of Solothurn decided to migrate its computers to Linux, but in 2010 the Swiss authority has made a U-turn by deciding to use Windows 7 for desktop clients.[75]

#### United Kingdom

## Education

Edubuntu CD kit

Linux is often used in technical disciplines at universities and research centres. This is due to several factors, including that Linux scales to run on very large systems that small home computer operating systems cannot. Rarely are 'license costs' or cost of software issues. The U.S. Department of Defense (DoD) uses Linux on its supercomputers because of security, stability and scalability. The DoD can afford licenses from anyone and doesn't worry about the cost. To some extent, technical competence of computer science and software engineering academics is also a contributor, as is stability, maintainability, and upgradability. IBM ran an advertising campaign entitled "Linux is Education" featuring a young boy who was supposed to be "Linux".[77]

Examples of large scale adoption of Linux in education include the following:

* The OLPC XO-1 (also called the MIT $100 laptop and The Children's Machine), is a low-cost laptop running Linux, to be distributed to millions of children, more so in developing countries, as part of the One Laptop Per Child project.
