** Description changed:
[Impact]
* mtx package has an arch-skew contents. On xenial and yakkety, on s390x, the
package was build with new enough bash-completion debhelper addon that has
placed the completion files into /usr which generates file conflict with
bash-completion package itself
* on all other architectures in xenial and yakkety the bash completion file
is shipped by the mtx package, redundantly in /etc, when there is a completion
file in /usr in bash-completion package already
* in zesty the bash completion file got remoted from the mtx package in favor
of bash-completion package one.
* to avoid file conflict on s390x on xenial/yakkety, I'm proposing to rebuild
mtx package on xenial and yakkety and remove the redudant bash completion file
[Testcase]
* Co-install mtx package and bash-completion package, without any file
conflicts
- * Verify that /etc/bash_completion/mtx file does not exist and/or is removed
during the installation of the new mtx package (that should happen on non-s390x
architectures)
+ * Verify that /etc/bash_completion.d/mtx file does not exist and/or is
removed during the installation of the new mtx package (that should happen on
non-s390x architectures)
* Verify that mtx bash completion is still available

Summary
=======
Machine: IBM z13, Ubuntu 16.04.01. uname -a
Linux s8314007 4.4.0-47-generic #68-Ubuntu SMP Wed Oct 26 19:42:36 UTC 2016
s390x s390x s390x GNU/Linux
We were unable to install the 'mtx' package for control of tape autochangers
via 'apt-get install mtx'
Details
=======
We wanted to install both the mt-st and mtx packages for s390 tape support.
We encountered a problem in the mtx_1.3.12-9_s390x.deb package which was
downloaded to /var/cache/apt/archives/ location but installation was not
performed due to duplicate bash completion data being delivered.
See the console output section below for results and more details about the
error itself.
We expect the mtx package to install smoothly with apt-get install mtx.
We worked around with:
