sudo systemctl start mongodFor some reason, DigitalOcean droplets, and perhaps other cloud providers, have /dev/random blocking problems. This probably is because they are running many small computers on a single Linux instance and the entropy pool dries up pretty quickly. If this doesn't make sense, install Haveged and don't worry about it.
If it does, libsodium, which is the public-private key cryptography library we use, uses /dev/random with no option to use /dev/urandom. Haveged solves this problem.
sudo apt-get install haveged -y
systemctl start haveged
systemctl enable havegedpip3 install lamden
