debootsnap/debrebuild cannot find the package below, needed to
reproduce a build via .buildinfo:

linux-libc-dev:amd64=7.1.5-1

Checked https://snapshot.debian.org/package/linux-libc-dev/7.1.5-1/
and the version is not listed there.

Encountered while running the salsa-ci "reproducible" pipeline job
for the 6tunnel package.

Control: tags -1 + moreinfo

There isn't an amd64 binary package for linux-libc-dev. It's
architecture-independent, so arch:all.

I'm assuming that's just a display issue, and that your failing build
is https://salsa.debian.org/damian/6tunnel/-/jobs/10019014

That build was run at 12:07. The amd64 build for src:linux version
7.1.5-1 finished at 11:37, so was quite possibly not in a location
where the salsa-ci job could find it at the time. If you retry the job
now, does it succeed?

That's because your URL form is wrong. The package needed there is a
source package, not a binary package.

https://snapshot.debian.org/package/linux/7.1.5-1/#linux-libc-dev_7.1.5-1
shows the package as expected.

I'm not seeing an issue with snapshot.debian.org in the above.

The buildinfo files only contains the host architecture, not
architecture of the individual packages.

Yes, that's due to salsa-ci using incoming.d.o in the original build.
The issue is tracked here:

https://salsa.debian.org/salsa-ci-team/pipeline/-/work_items/587

I would propose to close this bug.

Hi Adam and Jochen, Thanks for the clarification! I retried the job and it passed this time. THis confirms it was just a timing/propagation issue with the linux-libc-dev source package not yet being available on snapshot.debian.org at the moment the job ran, as you predicted.
I am closing this bug now.

Thanks again for looking into it,
Damian Daniel
