ソフトウェア プロパティ GTK Ubuntu 18.04 を起動すると UnicodeDecodeError エラーが発生する

Ubuntu 18.04 で software-properties-gtk を起動しようとすると問題が発生します。デスクトップ アイコンから起動しても何も起こらず、ターミナルから起動すると次のエラーが表示されます。

root:~# software-properties-gtk 
Traceback (most recent call last):

@user966203 の提案のおかげで、の出力を確認しましたapt-key list。
「é」文字が「\xe9」としてエンコードされているキーを見つけました。 これを次のように削除しました。
uid [ inconnue] Jean-Marc Le Peuv\xe9\x64ic <[email protected]>
apt-key del KEYID

同じ問題が（突然）発生しましたが...これは私にとってはうまくいきました（Google のどこかで見つけました）

sudo ナノ /etc/apache2/envvars

そしてこれを見つけます...

代わりにシステムのデフォルト ロケールを使用するには、次の行のコメントを解除します。

. /etc/default/ロケール

誰に感謝すべきか思い出せなくて申し訳ありません
