I know that Ubuntu 19.04 is not listed in the supported platforms and that only LTS versions of Ubuntu are, but I upgraded my laptop and found that I could no longer install or run MongoDB.  I mention this only in case it was not already known.

jim@jimbuntu:~$ sudo apt-get install -y mongodb-enterprise-server

jim@jimbuntu:~$

running mongod from a tarball installation gives:

Let me know if you need any more information.
