dnsdist: different names for the dnsdist 1.3.3 debug packages in Debian 9

[atosatto]

• Program: dnsdist
• Issue type: Bug report

Short description

With the 1.3.3 release, the name of the debug symbols packages for Debian Stretch have been renamed from dnsdist-dbg to dnsdist-dbgsym.
Note that in Jessie and all the Ubuntu derivates the debug packages are still named dnsdist-dbg.

This behavior appears not to be documented and, as a result, updating the dnsdist debug symbols packages or installing these using the name dnsdist-dbg used for all the debian-like distributions results in

root@debian-9:/# apt-get install dnsdist-dbg

Some packages could not be installed. This may mean that you have
requested an impossible situation or if you are using the unstable
distribution that some required packages have not yet been created
or been moved out of Incoming.
The following information may help to resolve the situation:

The following packages have unmet dependencies:
 dnsdist-dbg : Depends: dnsdist (= 1.3.2-1pdns.stretch) but 1.3.3-1pdns.stretch is to be installed
E: Unable to correct problems, you have held broken packages.

Environment

• Operating system: Debian
• Software version: Stretch
• Software source: PowerDNS repository

Expected behaviour

I would expect a consistent naming convention on the debug symbols packages across all the Debian-like distributions and the new name of the packages to be documented as a breaking change.

Actual behaviour

The installation of the debug symbols packages, using for instance http://github.com/powerdns/dnsdist-ansible, is broken on Stretch.

Afaict ...-dbgsym is the "future". Also the packages from debian (including stretch) are already named ...-dbgsym and are in a separate repository (see http://ftp.debian.org/debian/pool/main/d/dnsdist/ and http://debug.mirrors.debian.org/debian-debug/pool/main/d/dnsdist/).

Also see https://wiki.debian.org/AutomaticDebugPackages for some background.

Hi @stbuehler thanks for the very useful references.
This issue refers to repo.powerdns.com. We should probably do something similar to ftp.debian.org then.

xenial and newer should also get the dbgsym packages I think.

[atosatto]

Yeah, currently we have a bit of inconsistency because for xenial and bionic we ship the package as dnsdist-dbg.

Closing this as I believe we fixed it for current packages.
