Ubuntu 21.10 is called 'Impish Indri' -- here is when the Linux distro should be released Linux distributions and silly names go together like peanut butter and jelly. For whatever reason, the maintainers of these operating systems seem to enjoy having fun with what they call them -- some argue it is childish. Hell, even Google -- a multi- billion dollar company -- once used sugary dessert names for the Linux-based Android operating system. I am glad the search giant stopped that nonsense. One of the most well-known desktop Linux distributions to use funny names is Ubuntu. It famously uses the convention of an adjective and a lesser-known animal, each starting with the same letter. The letter is chosen sequentially by alphabet. For example, Ubuntu 21.04 uses the letter "H" -- "Hirsute Hippo".
