How do I build a .deb without zstd compression in Ubuntu 21.10?

Question

I'm building a .deb using dpkg-buildpackage on Ubuntu 21.10 that is then extracted in a Debian system, which does not use zstd compression. How can I switch to the old compression when building my deb?

Running the command with --compression=xz or the equivalent -Z flag still leads to a zstd compressed file.

I also cam across this and tried the compression flag, but it did not worked. Did you managed to came up with a solution to this problem? — AldegarRızvan, May 23 '22 at 12:55
Sorry no, my "solution" was to use a Docker container running an older Ubuntu version — Johannes Pertl, May 23 '22 at 14:23
Thank you for the response. Got now another compression format in my debian package, have a look at my answer. — AldegarRızvan, May 24 '22 at 08:46

You can make dpkg use another compression format by adding the following lines to the rules file, which is located in your debian folder:

override_dh_builddeb:
    dh_builddeb -- -Zgzip

It is a bit late, but I hope it helps somebody.

Thanks! Could you update your answer to include the location of the debian/rules file? – Johannes Pertl May 24 '22 at 11:30

The debian folder is in your project, which you want to build. Inside the debian folder, there is a rules file. You just have to append the text. – AldegarRızvan May 24 '22 at 14:17

Thanks! Note that indent must be tab, not spaces. Using spaces will cause a '*** missing separator' error – Ivar Simensen May 27 '22 at 08:58

If you're using dpkg-deb to build your deb add -Zxz to change the compression method from zstd to xz.

dpkg-deb -Zxz --build --root-owner-group yourdeb_1.1-0_amd64
