@brian-murray I'm really happy to see that there's finally a fix for
this, is it targeted for a SRU?

Title:
  "the cache has no package" error when wine update is available

Status in update-notifier package in Ubuntu:
  Fix Released
Status in update-notifier source package in Xenial:
  Triaged

Bug description:
  Release:

  $ lsb_release -rd
  Description:    Ubuntu 16.04 LTS
  Release:        16.04

  Pacakge:
  $ apt-cache policy update-notifier
  update-notifier:
    Installed: 3.168
    Candidate: 3.168
    Version table:
   *** 3.168 500
          500 http://gb.archive.ubuntu.com/ubuntu xenial/main amd64 Packages
          100 /var/lib/dpkg/status

  What should happen:

  $/usr/lib/update-notifier$ /usr/lib/update-notifier/apt-check -p
  wine-devel-amd64
  wine-devel
  google-chrome-stable
  winehq-devel
  wine-devel-i386

  What actually happened:

  $/usr/lib/update-notifier/apt-check -p
  E: Unknown Error: '<class 'KeyError'>' ("The cache has no package named 'wine-devel-i386'")

  Whats wrong:

  apt_check.py line 143:

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

  needs to use a full package name that includes the arch:

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

  There are many other reports of this problem - the suggested 'solution' in many cases is to run package manager/apt to install all the updates which then 'fixes' the problem until the next
  update for wine becomes available.
