Hi there!
I’ve got a beginner question, I just set up an old PC to be used as a media server with Plex.
I have Ubuntu server installed on the server.
I am wondering, can I also use it as a sort of makeshift file server?
And then access them with SFTP from my other PC?

Is that good enough? I mean it will work, but is Ubuntu Server and SFTP really everything I need to have a working server? What are the downsides?
