Hello there,

during a rebuild of the reverse b-d of libyaml I found that this package
failed to build on my amd64.

In addition, the build also failed on amd64, i386, arm64, and armhf,
each both in unstable and in bookworm, cf.
<https://tests.reproducible-builds.org/debian/rb-pkg/appstream.html>
where you will also find full logs.

The relevant part from my build log (hopefully, full log attached):

I can't reproduce this issue at all, and a recent upload of AppStream

Does this issue still exist? Maybe it was a fluke or fixed in some

Hello Matthias,

thank you for your reply and for the appstream update.

I agree that the new upload appears to be building just fine on the
official buildd, so thanks for that.

Unfortunately, for me both the previous version and the current version
still FTBFS on my local setup, with exactly the same error message. Of
course, that by itself could all too easily be a local fluke that I'd
have to investigate and that you could safely ignore, if it weren't for
reproducible-builds indicating the very same FTBFS as well.

Looking at the reproducible-builds history of appstream it seems it has
been FTBFS'ing in their setup for quite a while, cf.

https://tests.reproducible-builds.org/debian/history/appstream.html

as well as the individual logs at

https://tests.reproducible-builds.org/debian/rbuild/unstable/amd64/appstream_0.15.2-2.rbuild.log.gz
https://tests.reproducible-builds.org/debian/rbuild/unstable/i386/appstream_0.15.2-2.rbuild.log.gz
https://tests.reproducible-builds.org/debian/rbuild/unstable/arm64/appstream_0.15.2-2.rbuild.log.gz
https://tests.reproducible-builds.org/debian/rbuild/unstable/armhf/appstream_0.15.2-2.rbuild.log.gz
https://tests.reproducible-builds.org/debian/rbuild/bookworm/amd64/appstream_0.15.2-2.rbuild.log.gz
https://tests.reproducible-builds.org/debian/rbuild/bookworm/i386/appstream_0.15.2-2.rbuild.log.gz

https://tests.reproducible-builds.org/debian/rbuild/bookworm/armhf/appstream_0.15.2-2.rbuild.log.gz

All in all this hints at some issue still lingering around, but I cannot
exactly pinpoint what it might be.

I'd say let's wait until reproducible-builds attempts to build 0.15.3-1
and see what the results are. Or feel free to downgrade this issue here
as you deem fit, for on the official buildd and on your machine
everything seems to be working juts fine.

Cheers,
Flo

Hi Florian!

<florian_ernst@gmx.net>:

I'll likely downgrade this bug, but this is fairly odd! If the tests
fail on some building machines, there is a chance that the actual
application also doesn't work everywhere. I can say though that this
works on the buildds, on my local machine and on GitLab. Is there
anything that's different in the reproducible build machines compared
to the buildds? Is there anything special about your local machine?

Cheers,
    Matthias

Hello Matthias,

Well, apperently there is, and I'd love to know what exactly it is, but
I'm afraid I don't know. I am using sbuild just like the buildd do, but
reproducible-builds is using pbuilder (cowbuilder?), and all in all I
don't see any common factor.

That being said I take some strange consolation now from the weird fact
that appstream 0.15.3-1 seems to FTBFS on reproducible-builds as well,
or at least on amd64, arm64, and armhf so far, right in the same manner
as initially reported. Yeah, I know, that is not really helpful ...

Cheers,
Flo
