Could you please open a Terminal and run the the following command: "sudo aptd -td --replace" and try to repeat the action.

Afterwards please copy&paste the output here.

I just located the error. Thanks. But which application have you been using? Update-manager?

[Sebastian Heinlein (glatzor)]

Or software-center?
