Title:
  apt-check fails with "The cache has no package named 'skype-bin'"

Status in update-notifier package in Ubuntu:
  New

Bug description:
  I noticed today that I hadn't received any update notifications for a
  while, and after following the trail found in the output of /usr/lib
  /update-notifier/apt-check:

  E: Unknown Error: '<class 'KeyError'>' ("The cache has no package
  named 'skype-bin'")

  Removing the exception hook from that file we find the actual error:

  Traceback (most recent call last):
    File "/usr/lib/python3/dist-packages/apt/cache.py", line 198, in __getitem__
      return self._weakref[key]
    File "/usr/lib/python3.4/weakref.py", line 125, in __getitem__
      o = self.data[key]()
  KeyError: 'skype-bin'

  During handling of the above exception, another exception occurred:

  Traceback (most recent call last):
    File "./apt-check", line 201, in <module>
      run(options)
    File "./apt-check", line 136, in run
      ignored = ul._is_ignored_phased_update(aptcache[pkg.name])
    File "/usr/lib/python3/dist-packages/apt/cache.py", line 205, in __getitem__
      raise KeyError('The cache has no package named %r' % key)
  KeyError: "The cache has no package named 'skype-bin'"

  This occurs when checking for phased updates, it tries to index the
  apt.Cache with the package name from the apt_pkg.Cache. But since the
  arch is amd64 and not i386, the package in the apt.Cache is instead
  skype-bin:i386.

  If we replace:

  ignored = ul._is_ignored_phased_update(aptcache[pkg.name])

  with:

  ignored =
  ul._is_ignored_phased_update(aptcache[pkg.get_fullname(False)])

  Everything seems to work fine.
