I have upgrade my ubuntu from 21.04 to 21.10 and I have got the problem with install any packages after build it as deb file with this command
Code:
dpkg-deb -b DEB

I have got the compress file with tar.zst and that extension can not apply on dreambox

Code:
uses unknown compression for member 'control.tar.zst', giving up
How to build deb with tar.xz ?! Or How to download dpkg ?!!
