fr_FR.UTF-8 および C.UTF-8 ロケールは、ロケールリストで使用できないため使用できません。 [閉じる]

fr_FR.UTF-8ロケールはC.UTF-8ロケールリスト（提供）では利用できないためlocale -a使用できません。

追加する方法は次のとおりです。

編集1：私のシステムではlocale-gen少し古いので、パラメータを受け入れることができます（パッケージロケールv2.13）。

とにかく関連する他の方法/etc/locale.genも機能しません。

fr_FR.UTF-8ロケールは、指定されたC.UTF-8ロケールのリストではまだ使用できませんlocale -a。

どうすればいいですか？
