Parece que você tem certos repositórios que não têm zesty releases , então, temos System Settings --> Software & Updates --> Other Software e procuramos uncheck desses repositórios. Ao fechar, você será solicitado a atualizar suas informações de recompra, semelhante a fazer sudo apt update ou sudo apt-get update .
