Ubuntu manual installation guide wrong

precisely Following the manual installation of Rocket.Chat for Ubuntu 18.04LTS just throws me errors in journalctl about node things… fuse… fuse/future and whatnot.

I just would like to know why nobody has yet complained about the manual installation guide being outdated/wrong.
Why can’t Rocket.Chat just work out of the box, why is it so insanely complicated and has so many dependencies for specific versions of specific packages?

Server Setup Information

  • Version of Rocket.Chat Server: latest
  • Operating System: Ubuntu 18.04LTS
  • Deployment Method: manual install
  • Number of Running Instances: 1
  • DB Replicaset Oplog: 01
  • NodeJS Version: latest
  • MongoDB Version: latest
  • Proxy: nginx
  • Firewalls involved: -

I have a manual installation of Rocket.Chat running on another server (ubuntu 2004, rocketchat 3.7.1, node 12.14.0, mongo 4.0.21, npm 6.13.4) and I dare not updating this one.
I bet every even slightest smallest update will break everything and Rocket.Chat will refuse to work again.

Just use docker, this is a 3 node cluster. Can simply be changed to 1 node if you want to. Running node applications directly on the OS is asking for trouble.

version: '2'
