The South Korean government has announced plans to switch its 3.3 million PCs to Linux-based operating systems, aiming to reduce its reliance on Microsoft and cut software licensing costs. The migration is expected to cost around $655 million and will start with a pilot test to explore potential compatibility and security issues. The government has not yet indicated which Linux distribution it will use, but some departments are already using Ubuntu-based and Debian-based systems. The move is seen as a significant step towards open-source adoption in the public sector.
