Debian: 一貫性の悪い状態のパッケージを削除または再インストールしてください

パッケージ管理に問題があります。

ある時点でbluezパッケージが破損しているため、アップデートなどを中断したようです。アンインストールおよび/または再インストールしようとしましたが、エラーのみが発生しました。このパッケージが破損している限り、aptでは何もできません。

パッケージの出力を削除してみました。

$ sudo aptitude remove bluez 
The following packages will be REMOVED:

Debian テストを実行しています。これは実際にこの特定のパッケージの問題ですか、それともdpkgの問題ですか？パッケージマネージャを変更するにはどうすればよいですか？
