Debian アップグレード後に一部の Python プログラムを実行できない

昨日apt-get dist-upgradeはそうしましたが、今実行しようとすると次のエラーが発生しますanki。

Traceback (most recent call last):
  File "/usr/bin/anki", line 5, in <module>
    import aqt
  File "/usr/share/anki/aqt/__init__.py", line 12, in <module>
    from aqt.qt import *
  File "/usr/share/anki/aqt/qt.py", line 22, in <module>
    from PyQt4.QtWebKit import QWebPage, QWebView, QWebSettings
ImportError: No module named QtWebKit

私が実行しようとしたときcalibre：

  File "/usr/bin/calibre", line 19, in <module>
    from calibre.gui_launch import calibre
  File "/usr/lib/calibre/calibre/__init__.py", line 22, in <module>
    from calibre.startup import winutil, winutilerror

    from calibre.utils.icu import title_case, lower as icu_lower, upper as icu_upper

    raise RuntimeError('Failed to load icu with error: %s' % err)
RuntimeError: Failed to load icu with error: No module named icu

  import shutil

どんな助けでも大変感謝します。
