I havnt tried rebooting.
i dont really know how to as i am new to this.
Do you kno by any chance what the problem is.

When i type that command you told me to, all the repositories came back, but if i exit HAM they will go.

On the log it says:

hildon-application-manager 2.2.72
apt-worker: to weak to get lock from 3881.
apt-worker closed connection.
apt-worker is not running
apt-worker excited.
