rpm on ubuntu 16.04 fails to honor non-zero exit from preun scriptlet

[bugproxy]

---Problem Description---
rpm erase does not honour a non-zero exit code from preuninstall scriptlet.

---uname output---
Linux kanyu 4.4.0-22-generic #40-Ubuntu SMP Thu May 12 22:03:46 UTC 2016 x86_64 x86_64 x86_64 GNU/Linux

Machine Type = VMware

---Debugger---
A debugger is not configured

---Steps to Reproduce---
 Install the IBM MQ rpms
create and start a queue manager
attempt to uninstall ( rpm -qa | grep MQSeries | xargs rpm -e)
preuninstall scriptlets correct exit with status of 1 but rpm continues with erase.

This is occurring on x86_64, ppcle and Z
rpm on Ubuntu 14.4 and earlier behaved as expected, erase aborted on non-zero exit from preun

ats@kanyu:~$ apt list rpm

I sent a patch here : https://github.com/rpm-software-management/rpm/pull/74 .
Review seems positive, but we still need to wait for the merged.
I also opend the bug in Debian and sent the debdiff : https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=830194 .
Would it be possible to have the patch pushed in the packaging for 16.04 ?

[Frédéric Bonnard (frediz)]

Here is the debdiff that applies on top of rpm-4.12.0.1+dfsg1 .

[Steve Langasek (vorlon)]

Installing rpm packages on an Ubuntu system is not supported, at all; it's expected that one use 'alien' to convert packages from rpm to deb format before attempting to install them.

This bug therefore does not rise to the level of an SRU for 16.04.

Patch has been merged upstream. I asked if Debian Maintainer can embed the patch in the packaging. Let's see?

[Frédéric Bonnard (frediz)]

My patch has landed in Debian, as rpm 4.12.0.1+dfsg1-6 and it got synced in Ubuntu Yakkety.
