Ubuntu 16.04 dotnet installed but not working.

I installed dotnet core 2.0.6 on Unbuntu 16.04. Everything went smoothly. 

If I type 

> dotnet

I get 

Usage: dotnet [options]
Usage: dotnet [path-to-application]

Options:
-h|--help Display help.
--version Display the current SDK version.
--list-sdks Display the installed SDKs.
--list-runtimes Display the installed runtimes.

path-to-application:
The path to an application .dll file to execute.

So far so good. 

If i type > dotnet --info

I get.. 

Microsoft .NET Core Shared Framework Host

Version : 2.0.6
Build : 74b1c703813c8910df5b96f304b0f2b78cdf194d

Now if i type > dotnet --version  or dotnet new console I get this error.. 

Did you mean to run dotnet SDK commands? Please install dotnet SDK from:

I clearly is installed.. What is the issue here??
