I have a csv file in Ubuntu 16.04 version. I want it to be upload into SharePoint list via power shell.

PowerShell core is probably not going to be your best option because the main SharePoint client libraries are not going to be compatible with it.
I'd suggest a Node.js app using PnPJS. here's a guide to getting started with that:
You're going to need to parse the CSV and upload the list items in a loop.
