Install the software repo.

$ sudo curl -o /etc/apt/sources.list.d/microsoft.list https://packages.microsoft.com/config/ubuntu/18.04/prod.list

Run a repository update.

$ sudo apt update

Quote from the Microsoft link at top of this article:

When installing a PowerShell Core Preview release for Linux via a Package Repository, the package name changes from powershell to powershell-preview.

Install the powershell software. 18.04 has the powershell-preview

$ sudo apt-get install -y powershell-preview

Start powershell. The non preview way is just pwsh

$ pwsh-preview                      
PowerShell 6.1.0-rc.1
