Has anyone here had some experience creating a Debian / Ubuntu package? I am trying to backport the lammps package (http://packages.ubuntu.com/quantal/lammps) from Ubuntu 12.10 (Quantal) to Ubuntu 12.04

I only need it unofficially - just need a .deb package for convenience's sake when creating custom virtual machine images for deployment to IaaS platform.

Following the Ubuntu Packaging Guide at https://wiki.ubuntu.com/PackagingGuide , I can build successfully, except when I try to rebuild using the debuild command, I usually get this error:

 dpkg-source: error: aborting due to unexpected upstream changes, see
 /tmp/lammps_0~20120615.gite442279-1.diff.aie32n dpkg-source: info: you
 can integrate the local changes with dpkg-source --commit
 dpkg-buildpackage: error: dpkg-source --include-binaries -i -b
 lammps-0~20120615.gite442279 gave error exit status 2

Running 'make clean-all' at the src directory still does not solve the problem. Is there any way to completely clean off all the files that were generated during the build process, or to ask debuild to ignore any differences in the source files?

This means you have applied changes to the unpacked upstream source which are not part of a patch in the debian/patches/ directory, or listed in the series file in there if they are; and/or there is some inconsistency in the state of quilt's application of the patches.

Looking at the mentioned file in /tmp will show you the changes in question.

  • Thank you very much for the quick answer!Is there a quick way to restore the changes done by 'make' instead of undoing all the changes record in the /tmp/*diff* file? – hanxue Dec 8 '12 at 9:08

Avoid the Debian bureaucracy by just building the binary: dpkg-buildpackage -b

    This is not so useful if you intend to upload to debian. – jeremiah Jul 13 '17 at 22:22

    @jeremiah but very useful if you're tweaking a debian package for personal use. – Wyatt8740 Jan 8 at 20:28

change the format in debian/source/format from 3.0 (quilt) to 3.0 (native) if you do not want to use quilt. This solved the problem for me anyway.

  • THIS! Quilt is impossible. – Jay _silly_evarlast_ Wren Apr 10 '15 at 19:47

    I naively followed this comment as is. The net effect will be that your build will no longer use the patches in debian/patches. Could you please expand on the answer by explaining how you add the necessary magic to debian/rules to actually apply the patches? – Thomas Vander Stichele Apr 14 '15 at 19:39

@Thomas Vander Stichele

I have come up with a workaround that uses the generated temporary file as a patch: https://www.theo-andreou.org/?p=1112#toc-apply-patches-for-policy-compliance

I saw this problem when quilt incorrectly thought I had applied patches to my working copy (you can find its current status in the .pc folder). The fix in that case was to force quilt to pop all the patches with quilt pop -a -f.
