hweb: в Ubuntu не найдено ни одного шаблона

Я недавно обновил Mercurial на своем сервере, и теперь я получаю следующие ошибки для моего скрипта hgweb.cgi. Когда я ищу его в Интернете, я нахожу только учебники по настройке для машин Windows, говорящих о шаблонах, и даже они не указывают, где взять шаблоны. Может ли кто-нибудь помочь мне снова запустить мой сервер?
