if update manager doesnt work you should update by terminal by using this command : "sudo apt-get update" then it will require passwod of your main user. this will check for updates . And now to install updates use this command: "sudo apt-get upgrade"
this will ask you to that do you really want to upgrade press y and then enter. now you are updated.

First you need to update the repositories list with command:

sudo apt-get update

and after this you can try to upgrde the system packages with the command:

sudo apt-get upgrade

And update the ftp server key with sudo apt-key update command, if necessary.

Good luck

Thanks Cristi Nistor, that solved my question.
