Ceph » devops

We cannot build Ceph nautilus on Ubuntu 16.04 although it is said that this version is all the time supported on Ubuntu 16.04 (https://docs.ceph.com/en/latest/start/os-recommendations/).
install-deps.sh script returns error:

E: Malformed line 1 in source list /etc/apt/sources.list.d/libboost.list (type)
E: The list of sources could not be read.
E: Malformed line 1 in source list /etc/apt/sources.list.d/libboost.list (type)
E: The list of sources could not be read.

But the real problem is that this gateway has timed out:
https://shaman.ceph.com/api/repos/libboost/master/1d7c7a00cc3f37e340bae0360191a757b44ec80c/ubuntu/xenial/repo
so the command:
curl --silent --location https://shaman.ceph.com/api/repos/libboost/master/1d7c7a00cc3f37e340bae0360191a757b44ec80c/ubuntu/xenial/repo --output /etc/apt/sources.list.d/libboost.list
cannot load all needed information to install all dependancies.
