This is usually caused by the unix user you are logging in as not having a valid shell. or ssh settings.

The "can't open /dev/tty" bit near the end is the giveaway.  Try logging in manually, you will probably get the same error. 

If you do, then you will need to log in as another user (one who can use su or sudo to change other user's accounts), and look at why that user cannot log in (make sure they have a shell and home directory set in /etc/passwd, and that their home directory exists, belongs to them and they can read/write it).  Try "su - <username>" first to see what that does. it might tell you more about what the problem is

If you can log in, or you've fixed the account as above, then you'll want to check what is in the .ssh directory in their home directory.

I am able to login from my local system with same user 

[Nic Brough -Adaptavist-]

So, from your system, you can use "ssh ubuntu@x.xxx.xx.xx" and get a command prompt?

What is in that user's .ssh directory in their home directory?

[mohan_b]

yes,

I have resolve my issue by following
