# Problem

aptly cannot handle Zstandard compressed control.tar.zst and data.tar.zst
within debian package.

# How to reproduce

  [!] Unable to read file ....deb: unsupported tar compression in ...amd64.deb:
control.tar.zst
  [!] Some files were skipped due to errors:

For example, handle packages which is built on Ubuntu 22.04 causes this issue.


# Additional information

Upstream supports Zstd compression already, but not shipped yet.

  Add support for zst compression
  https://github.com/aptly-dev/aptly/pull/1050


As a workaround, use dh_builddeb -- -Zxz [1] when building package
if you can control package build process.
