16.04 - This command can only be used by root - Ask Ubuntu
i'm on ubuntu 16 , i'd add neo4j package. tried in 3 ways leading same error.
these attempts:
wget -o - http://debian.neo4j.org/neotechnology.gpg.key | apt-key add - sudo wget -o - http://debian.neo4j.org/neotechnology.gpg.key | apt-key add - sudo -i wget -o - http://debian.neo4j.org/neotechnology.gpg.key | apt-key add -
but error message:

you need change wget command from:
sudo wget -o - http://debian.neo4j.org/neotechnology.gpg.key | apt-key add -
to:
sudo wget http://debian.neo4j.org/neotechnology.gpg.key | apt-key add -
from man pages wget...
