Не получается поставить mongodb?

Не ставится mongodb на ubuntu12.04
apt-get install mongodb-server
mongodb-server : Depends: mongodb-clients but it is not going to be installed
Depends: libboost-filesystem1.46.1 (>= 1.46.1-1) but it is not going to be installed
Depends: libboost-program-options1.46.1 (>= 1.46.1-1) but it is not going to be installed
Depends: libboost-system1.46.1 (>= 1.46.1-1) but it is not going to be installed
Depends: libboost-thread1.46.1 (>= 1.46.1-1) but it is not going to be installed
Depends: libpcrecpp0 (>= 7.7) but it is not going to be installed
Depends: libstdc++6 (>= 4.6) but it is not going to be installed

Это зависимости тоже не ставятся, apt-get install -f не помогает. dpkg --configure -a тоже. Есть идеи?
