再インストールを希望するpython3を削除しましたが、実行できません

$ cat /etc./issue
$ Ubuntu 18.04.1 LTS

Sorcesからpython3.6とpython3.7をインストールしました。今、私はgnome-terminalをインストールしようとしています（これは、何らかの理由でpython3とともに削除されました）、次のコマンドを実行します。

$ Sudo apt-get install gnome-terminal

その行が実行され、次の出力が生成されます。

python3ですが、インストールされています。

$ python3 --version
$ Python 3.6.5

私が試した場合：

$ Sudo apt-get install python3

次のエラーが発生します。

私が試した場合：

など...どうすればいいですか？私は完全にアイデアを使い果たしました...

あなたは適性を試すことができます：

  1. 次のようにaptitudeをインストールします：

    Sudo apt install aptitude

  2. 次のようにpython3をインストールします。

    Sudo aptitude install python3

Aptitudeは依存関係の解決に優れており、おそらくあなたの場合は成功するでしょう。
