Debian’s dpkg package doesn’t support zstd compression ?

[Haraade]

Build, from source.
sudo dpkg -i linux-image-current-odroidxu4_22.05.0-trunk_armhf.deb

dpkg-deb: error: archive 'linux-image-current-odroidxu4_22.05.0-trunk_armhf.deb' uses unknown compression for member 'control.tar.zst', giving up

This is happening on Buster or Bullseye?

Bullseye

@The-going any clues?

I don't know yet. I do not test and do not build debian.
But maybe the question is in the configuration?

@Haraade Forgive my inattention. Tell me which operating system the package was built on.

Build in docker. Host Os, Ubuntu jammy.

[pyavitz]

either add to the packaging patch or mod the builddeb to force xz.

-	dpkg --build "$pdir" ..
+	dpkg-deb -Zxz --build "$pdir" ..```

Or, someday we will start collecting packages for a specific operating system inside this native OS.
Even using cross compilation.

[igorpecovnik]

inside this native OS.

Yes, we are preparing that. https://github.com/armbian/build/actions/runs/2276249931 but this is yet another subsystem that would need to be maintained in order to work without (other) issues.

@igorpecovnik Don't mind my grumbling. I am slowly moving in this direction, but very slowly.

I think we can set this compression by default if not set.

This needs to be tested.

Me too ;) This is something for future, low priority. I have added to CI just to monitor how fragile this is.

This is something for future, low priority.

This is a serious question for me. Today I have to limit myself to only one operating system, the one that is currently in the VM.
