I have Kubuntu 18.04 installed on my machine and I installed PowerShell Core following the instructions given: Installing PowerShell core in linux.

I then setup the remoting following the steps described here: PowerShell remoting over SSH.

Even though the steps target Ubuntu 14.04, I could make my way through them.

But when I am trying something as simple as executing something on my own machine through remoting I get:

PS /etc/ssh> Invoke-Command -ComputerName ehouarn-perret-ThinkPad-E460 -ScriptBlock Write-Output Hello 
Invoke-Command : MI_RESULT_ACCESS_DENIED
At line:1 char:1
+ Invoke-Command -ComputerName ehouarn-perret-ThinkPad-E460 -ScriptBloc ...
+ ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+ CategoryInfo : InvalidOperation: (:) [Invoke-Command], PSInvalidOperationException
+ FullyQualifiedErrorId : InvalidOperation,Microsoft.PowerShell.Commands.InvokeCommandCommand

Any idea how to make the PowerShell Core remoting work with Ubuntu?

As stated by LotPings:

Your 2nd link requires to use [-HostName <string>] [-UserName <string>]

#
# Linux to Linux
#
$session = New-PSSession -HostName UbuntuVM1 -UserName TestUser

I tried:

ehouarn-perret@ehouarn-perret-ThinkPad-E460:/etc/ssh$ pwsh-preview

Seems it works like a charm, my bad!
