А вот это неправильно. Должно быть ru_UA.UTF-8 (регистр и дефис имеют огромное значение).

muromec@lightmare  ~ % egrep -v '^#' /etc/locale.gen                                                    100 50.0 on
ru_UA.UTF-8     UTF-8
muromec@lightmare  ~ % sudo locale-gen                                                                  100 49.0 on
