[Brian Murray]

Hello Balint, or anyone else affected,

Accepted update-manager into artful-proposed. The package will build now
and be available at https://launchpad.net/ubuntu/+source/update-
manager/1:17.10.14 in a few hours, and then in the -proposed repository.

Please help us by testing this new package.  See
https://wiki.ubuntu.com/Testing/EnableProposed for documentation on how
to enable and use -proposed.Your feedback will aid us getting this
update out to other Ubuntu users.

If this package fixes the bug for you, please add a comment to this bug,
mentioning the version of the package you tested and change the tag from
verification-needed-artful to verification-done-artful. If it does not
fix the bug for you, please add a comment stating that, and change the
tag to verification-failed-artful. In either case, without details of
your testing we will not be able to proceed.

Further information regarding the verification process can be found at
https://wiki.ubuntu.com/QATeam/PerformingSRUVerification .  Thank you in

Bug description:
  [Impact]

  Empty directories can't be stored in Git, which is a very popular
  version control system for maintaining source packages.

  Keeping the empty directory in the source package prevent others from
  easily contributing to the package by importing it in full to a local
  repository, making changes, then generating an updated source package
  with tools like git-buildpackage. In that workflow the empty directory
  would be lost potentially causing errors if the installed binary
  package relied on it or causing autopkgtest failures if tests used it.

  The backport to a stable release helps further maintenance of the
  package in git-based workflows and avoids accidentally breaking
  autopkgtests when the existence of the empty dirs matter.

  The upload may drop the empty dirs or place placeholder (e.g.:
  */.keep) files  in the source package.

  [Test Case]

  Extract the source package, then run the following command int the
  extracted source directory:

   find . -depth -type d -empty

  [Regression Potential]

  The removed directories or the added placeholders may cause run-time
  issues or cause autopkgtest failures. To prevent those please check
  that the placeholder files are not shipped in the binary packages and
  also run autokgtests.
