[apport] apt-check crashed with ImportError in <module>()

[Filiprino]

Binary package hint: update-notifier

I was downloading new updates from Update Manager, and while doing it, a message warned me that the update notifier crashed.
PS: While writing this text, it crashed again (1 package was left to install, because it couldn't be installed, package name: hot-keys).
