Я не могу инициализировать мою базу данных на Ckan. Я пытаюсь установить Ckan 2.8 на Ubuntu 16.04 и Postgres 9.6, и я следовал инструкциям на официальном page .
Все хорошо, но когда я пытаюсь инициализировать свою базу данных, я не могу.
Это ошибка.

sqlalchemy.exc.ProgrammingError: (psycopg2.ProgrammingError) no existe la secuencia «package_extra_revision_id_seq»
[SQL: 'drop sequence package_extra_revision_id_seq;']
Я пытаюсь запустить:
- paster db init -c /etc/ckan/default/production.ini
- sudo ckan db init
Я проверил свою базу данных во время работы сценария, и сценарий правильно создал последовательность "package_extra_revision_id_seq". Но когда сценарий завершает, последовательность "package_extra_revision_id_seq" больше не существует.
