Ошибка установки datastax cassandra 2.0

Question

Я не могу установить datastax cassandra 2.0 в Ubuntu. Я могу установить 2.1 без проблем, но мне нужно запустить 2.0.9. Я следую за этими шагами, есть ли что-то, что я могу сделать, чтобы установить 2.0?

echo "deb http://debian.datastax.com/community stable main" | sudo tee -a /etc/apt/sources.list.d/cassandra.sources.list
curl -L http://debian.datastax.com/debian/repo_key | sudo apt-key add -
sudo apt-get update
sudo apt-get -y install  dsc20

и ошибка:

$ sudo apt-get -y install  dsc20
