The new Ubuntu 23.10 release has been codenamed Mantic Minotaur, and Canonical is now using a completely non-existent creature.

Ubuntu distributions are often named after endangered animals such as the pangolin, and then a modifying adjective is added.
Mantic” is derived from the Greek words mantikos and mantis, which relate to divination or prophecy, and translates to “seer”. The Minotaur is a famous half-man, half-bull monster in Greek mythology.
Canonical has announced that the Ubuntu 23.10 release will be released on October 12, with the beta version to be released on September 21.
Ubuntu 23.10 is not an LTS release and the support cycle is only 9 months long. For those who are more focused on stability, it’s best to stick with Ubuntu 22.04 LTS until Ubuntu 24.04 LTS is released in April next year.
