Ubuntu 6.10, codenamed Edgy Eft, was released in October 2006 as part of Canonical's free Linux distribution. Its startup sound belonged to the default Ubuntu sound theme of that era, played automatically at login after the desktop environment loaded. Unlike later releases that shortened or removed login sounds, this version is remembered by the open source community and preserved on soundboards and in archives. It remains popular in retro computing circles, where creators use it to instantly date a machine or evoke mid-2000s desktop nostalgia.
