Install on Raspian

I already have a rpi 3 that has raspian 9.11 on it and would like to install it but cant seem to get it to update. this is what i get

pi@raspberrypi:~ $ sudo apt-get install nymea-networkmanager dirmngr
E: Malformed line 2 in source list /etc/apt/sources.list.d/nymea.list (type)
E: The list of sources could not be read.

I already have other software on it for our cloud services we provide. We presently are also using on it the zwave me for our integration to zwave locks and our cloud but would like to test if nymea would be a better more reliable fit for our Gateway.

There is something wrong in the repository file, as the error message youve posted says, line 2
