これはDebian 8.5のKazamでPython3の依存関係が欠落しているバグですか？

入力に関連するエラーを記録しようとしましたが、Kazamがrootと非rootとして機能することはできません。下記をご覧ください。apt-get install kazam ffmpeg正常にインストールしましたが、エラー/警告のため誤ってインストールされました。

rootでこれを行い、apt-get updateもう一度apt-get upgrade繰り返しましたが、問題は解決しません。

python --versionKazamがpython3を望むかもしれないと思いましたが、Python 2.7.9（与えられた）に問題があり、依存関係が欠落している可能性がPython 2.7.9あります。どうやって進めますか？
