ラケットのパッケージをインストールするには？

Question

私はUbuntu OSユーザーです。私は、コマンド

$ raco pkg install sicp 

を次のようにラケット用のパッケージをインストールしようとしている。しかし、私は私のシステムでこのコマンドを実行したとき

$ raco pkg install sicp 
ssl-connect: connect failed (error:14077438:SSL routines:SSL23_GET_SERVER_HELLO:tlsv1 alert internal error) 
    context...: 
    /usr/share/racket/collects/openssl/mzssl.rkt:1207:8: loop

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

以下に示すように、私は理解していない予期しないエラーが発生しました、なぜそれは起こっている？このエラーを解決するのを手伝ってください。

これを実行しているときは、インターネットに接続していないようです。私は同じことをやろうとし、次のインストールに成功しました：
