** Description changed:

  [Impact]
  
  * I would like to propose a one-off full backport of unattended-upgrades
  1.2ubuntu1 to Bionic, Artful, Xenial and possibly Trusty releases because selectively backporting fixes for crashes and for issues that made u-u unreliable would be more risky thanks to the huge number of fixes and the
  inter-dependencies between them.
  
  [Test Case]
  
  * Since this backport involves fixing several bugs and this bug itself
  covers the full backport this is an overview of all LP bugs the upload
  fixes:
  
  - most important bugs (feel free to add more)
     + LP: #1615381 : apt-get autoremove may remove current kernel
  
  All LP bugs fixed by the backport, comments are welcome:

  [Regression Potential]
  
  * Due to this update covering the full backport unattended-upgrades can
  regress in any imaginable way including failing to install, upgrade,
  run, or removing essential packages from the system. Those are
  unlikely.* There are open bugs about u-u being slower than in the past,
  thus this may be a likely regression but IMO the pending speed
  optimizations should not be blocking the backport because the
  reliability issues are more important to fix and speed optimizations can
  be cherry-picked later.
  
  [Other Info]
  
  I asked for an exception for the package in following the SRU process:
  https://lists.ubuntu.com/archives/ubuntu-release/2018-May/004479.html
  
  I'm preparing the backport in ppa:rbalint/scratch and also run
  autopkgtests on it in addition to testing it manually in VMs.
  
  [Original Bug Text]
  
  Changes to support day-of-week patching and logging to syslog were added
  to upstream (https://github.com/mvo5/unattended-upgrades) over a year
  ago. These changes are not present in the latest Xenial nor Trusty
  packages (0.90 and 0.82.1) - requesting that these changes be pulled
  from upstream.
