Debian_10 build failed on OBS: dpkg-source: error: can't build with source format '3.0 (native)'

[munix9]

Describe the bug Debian_10 x86_64 v1.7 master build on OBS failed: dpkg-source: error: can't build with source format '3.0 (native)': native package version may not have a revision Ubuntu builds are fine.

To Reproduce Steps to reproduce the behavior: See https://build.opensuse.org/package/live_build_log/home:munix9:unstable/celestia/Debian_10/x86_64

Expected behavior Debian_10 build should not fail. Maybe a problem with latest updates for Debian_10 and the definition in https://github.com/CelestiaProject/Celestia/blob/master/debian/source/format (should be 3.0 (quilt) ?!).

Screenshots If applicable, add screenshots to help explain your problem.

Desktop (please complete the following information): Debian_10 build on OBS.

Additional context Add any other context about the problem here.

Hi @munix9 ,

This is a problem on OBS side:

What is debian.tar.xz purpose? If this is something you created then please update its debian/source/format to 3.0 (quilt). Or better avoid its usage if it's possible.

[munix9]

No, I don't think that's a problem with OBS. I created the debian.tar.xz manually for testing, normally this is created by OBS using the _service file. The manually generated debian.tar.xz is identical to the content of the debian folder, with the difference that the debian/source/format file now contains 3.0 (quilt) instead of 3.0 (native). Apparently something has changed recently with Debian 10, so that the above error message appears during the build when 3.0 (native) is used.

Or better avoid its usage if it's possible.

No, this is required for building on OBS, has nothing to do with it and is normally generated automatically from _service file as described above (see also https://build.opensuse.org/package/view_file/home:munix9:unstable/celestia/_service?expand=1 - currently the section is disabled because of testing). After all, it worked before.

I will create a request for it.

Could you apply patches to generated debian.tar.xz?
