コンションといいます。よろしくお願いします。

会社で使っているUbuntu11.10ですが、アップデートする度に、その過程の最後に表記のエラーメッセージが表示さます。
無視して「閉じる」ボタンを押し下げることもありますが、もし不具合が起こったらと気になっております。
このエラーメッセージは毎回、常にアップデートの最終段階で表示されます。

アップデートが正常に出来ているのか否かなどの確認をするため、アプリケーションソフトを起動し
ヘルプなどからバージョン情報を見てみると、正常にアップできているようです（確信はありませんが）。


パッケージ更新情報に異常があるのかもしれませんが、どうしたら良いのでしょうか？
よろしくお願いします。

参考までに、エラーの詳細が表示されてますので、コピーアンドペーストで下記に記します。
