Title:
  Unattended-upgrades may crash when a package does not have a candidate

  Fix Released
Status in unattended-upgrades source package in Bionic:
  Fix Committed
Status in unattended-upgrades source package in Cosmic:
  Fix Committed
Status in unattended-upgrades source package in Disco:

Bug description:
  [Impact]

   * Unattended-upgrades may crash when a package in apt's cache does not have 
a candidate and it is visited when finding packages to adjust.
   * The crash occurs when apt.Package.candidate is None and the fix is 
checking if .candidate is truthy and it that case is safe to reference the 
.dependencies attribute.

  [Test Case]

   * Watch the error not happening anymore.

  [Regression Potential]

   * The fix is very small and is not likely to cause any regression.
