E: Пакет 'maven2' не имеет никакого кандидата установки

Я пытаюсь установить знатока с sudo apt-get install maven2

Должно быть довольно простым, но я получаю это:

Reading package lists... Done
Building dependency tree       
Reading state information... Done
Package maven2 is not available, but is referred to by another package.
This may mean that the package is missing, has been obsoleted, or
is only available from another source
However the following packages replace it:
  maven

E: Package 'maven2' has no installation candidate

Какая-либо подсказка?

Спасибо
