Ubuntu 16.04 中的 update-notifier-common 错误

Ubuntu 16.04 中的 update-notifier-common 错误

我总是收到一个错误,提示Ubuntu 16.04 has experienced an internal errorUI 正在加载。我检查了原因,发现:-

ExecutablePath:-
  /usr/lib/update-notifier/package-data-downloader
Package:-
  update-notifier-common 3.168.8
ProblemType:-
  Crash
Title:-
  package-data-downloader crashed with ImportError in /usr/lib/python3/dist-packages/debian/deb822.py: No module named 'chardet'

追溯:-

Traceback (most recent call last):
  File "/usr/lib/update-notifier/package-data-downloader", line 24, in <module>
    import debian.deb822
  File "/usr/lib/python3/dist-packages/debian/deb822.py", line 38, in <module>
 ImportError: No module named 'chardet'

由此,我只能明白这个问题的根源update-notifier-common。请告诉我如何解决这个问题,报告错误没有帮助。
