Canonical has set a big challenge for Ubuntu: 200 million users by 2015.
Mark Shuttleworth, the founder of open-source support firm Canonical, made the prediction at an Ubuntu summit in Budapest, Hungary.
"[Our] goal is 200 million users of Ubuntu in four years," he said, according to a report on an Ubuntu blog.
"We’re not playing a game for developers' hearts and minds – we’re playing a game for the world's hearts and minds," he said. "And to do that we need to play by a new set of rules."
Last year, a Canonical employee estimated that Ubuntu had 12 million users globally.
Shuttleworth also accepted criticism over the Unity interface in the latest version of Ubuntu, called Natty Narwhal. "It’s perfectly normally for debate and questions around transitions like the one we made in Natty," he said.
