Installing PowerShell on Linux
Note: Ubuntu 20.04 is an LTS release. PowerShell does not currently support this version. Support for this version is being considered for the PowerShell 7.1 release. PowerShell can only support the distributions that are supported by .NET. See the Core release notes for a list of supported distributions.
