Zookeeper не присоединится к кластеру. Как применить патч / апгрейд?

Я использую ансамбль zookeeper из 3 узлов на ubuntu 14.04. Заметив, что node1 не запущен, мне пришлось удалить снимки этого узла, и теперь сервер действительно запустился, но отказывается присоединиться к кластеру.

Это журнал от zookeeper:

Похоже, что в версии 3.4.5 есть ошибки, и это было исправлено в 3.4.6, поэтому вопрос теперь в том, как применить патч или как обновить в Ubuntu 14.04.3?
