libjack-dev causes held broken packages

[jogness]

If libjack-dev is added as a package, the log.txt shows:

Unable to correct problems libjack-dev

A further investigation shows that the reason for this (the exception text) is:

E:Unable to correct problems, you have held broken packages.

A dependency of this package requires preseeding. I added this to my XML file:

<project>
...
    <preseed>
        <conf owner="jackd2" key="jackd/tweak_rt_limits" type="boolean" value="true"/>
    </preseed>
</project>

The package is installed in the rootfs and the preseeding did work. Both "dpkg --get-selections" and "dpkg -l" show that there are no partially installed or broken packages.

However, the libjack-dev package is not listed in the source.xml so something has gone wrong even though the rootfs seems to be fine.

I found some more information:
The interesting package (dependency) is jackd2. In the project directory of elbe I see:

• in the chroot directory, jackd2 is installed
• in the target directory, jackd2 is not installed

How can a package installed in chroot disappear in target?

I stumbled on some more information. At the very end of the log.txt, after elbe seems to do one last "apt-get update", I see the following (notice the removing and something special with the jack packages):

I tried building for armhf for buster, bullseye having "libjack-dev" included in package-list. And with elbe 14.4, I could not see any problems. I guess this issue can be closed now.

[bgermann]

The target system is stretch. @jogness Do you still need this to be fixed?

[jogness]

Since this bug was opened, I have switched to libjack-jackd2-dev. So I no longer need libjack-dev. However, since virraaj says it is working now, this issue can be closed anyway.
