This is a step by step process if Ubuntu image is fresh and would like to try PowerShell.
There could be some dependency issues with the default image that are covered here keeping in mind the beginners in Linux, like me.
Get the deb package from
https://github.com/PowerShell/PowerShell/releases/download/v6.0.0-alpha.9/powershell_6.0.0-alpha.9-1ubuntu1.14.04.1_amd64.deb
This would have some dependencies.
libc6
libunwind8
libicu52
before installing the dependencies, i would recommend to check the current installed packages with the following commands
apt list | grep libunwind8
apt list | grep libicu52
apt list | grep libc6
Obviously the source list wont be built if your image is new, so ensure that the package source is updated first before you try to install them with apt-get.
Go to Software & Updates and select 'Main Server'
Then update the pkg details with
Update source command.
apt-get update.
Then you should be good to go with the installation of missing packages.
In a new image the following package 'libunwind8' would be missing ..
Install 'libunwind8'
Then install PowerShell deb package.
TaDa!
Happy Scripting...
