some confusion regarding package updates

[Tapas Mishra]

I have some confusion regarding a server of mine.
When ever I ssh into it I see following message

  Graph this data and manage this system at https://landscape.canonical.com/

125 packages can be updated.
77 updates are security updates.

You have new mail.

So does this message mean that it is not getting updated.
If yes then let me know what should I be checking.
Because when I do an ssh into the server and manually do an aptitude update
I see messages like this
