Как установить пакеты для ракетки?

Question

Я Ubuntu Пользователь ОС. Я пытаюсь установить пакет для ракетки, как следующей команде

$ raco pkg install sicp 

Но когда я запустил эту команду в моей системе, я получил неожиданную ошибку, как указано ниже

$ raco pkg install sicp 
ssl-connect: connect failed (error:14077438:SSL routines:SSL23_GET_SERVER_HELLO:tlsv1 alert internal error)

    /usr/share/racket/collects/raco/raco.rkt: [running body] 
    /usr/share/racket/collects/raco/main.rkt: [running body] 

Я не понимаю, почему это происходит? Пожалуйста, помогите мне решить эту ошибку.

Похоже, что у вас нет подключения к Интернету, когда вы используете это. Я попытался сделать то же самое и получить следующую успешную установку:
