Missing dependency on dbus

[Wolfgang Karall-Ahlborn]

[Impact]

 * Pacemaker can be disfunctional and uninstallable if dbus is not around

[Test Case]

 * lxc launch images:ubuntu/yenial/amd64 xenial-pacemaker-bug1595901
   lxc exec xenial-pacemaker-bug1595901 /bin/bash
   apt-get remove --purge dbus # should not be installed anyway yet
   # for proposed verification enable proposed before the next step
   apt-get install pacemaker # should pull in dbus and work

[Regression Potential]

 * since this is not a change to source or build of the code the
   regression potential should be low.

 * if dbus is causing trouble somewhere it will now do so wherever
   pacemaker is installed, but as reported in the bug pacemaker just
   requires dbus, so there is no doubt in adding the dependency.

---

The systemd unit pacemaker.service depends on dbus.service, but the package has no Dependency on the dbus package, so on a system without dbus you get:

Confirmed, already for later on in the SRU template full steps to recreate:

lxc launch images:ubuntu/yakkety/amd64 yakkety-pacemaker-bug1595901
lxc exec yakkety-pacemaker-bug1595901 /bin/bash
apt-get remove --purge dbus
apt-get install pacemaker

I believe this was fixed in Yakkety by 1.1.15-1ubuntu1

Since the merge of pacemaker is now in that brought this change into the devel release it is time to SRU this simple change to fix it in Xenial as well.

Xenial debdiff uploaded. Thank you!

Hello Wolfgang, or anyone else affected,

Accepted pacemaker into xenial-proposed. The package will build now and be available at https://launchpad.net/ubuntu/+source/pacemaker/1.1.14-2ubuntu1.1 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 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 to verification-done. If it does not fix the bug for you, please add a comment stating that, and change the tag to verification-failed. In either case, details of your testing will help us make a better decision.

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

Version 1.1.14-2ubuntu1.1 works for me.

[Brian Murray (brian-murray)]

The verification of the Stable Release Update for pacemaker has completed successfully and the package has now been released to -updates. Subsequently, the Ubuntu Stable Release Updates Team is being unsubscribed and will not receive messages about this bug report. In the event that you encounter a regression using the package from -updates please report a new bug using ubuntu-bug and tag the bug report regression-update so we can easily find any regressions.

[Launchpad Janitor (janitor)]

This bug was fixed in the package pacemaker - 1.1.14-2ubuntu1.1
