# hifiberry-audiocontrol declares Breaks: hifiberry-bluetooth (<< 1.0.6), so
# unpacking a newer audiocontrol over an older bluetooth makes dpkg deconfigure
# bluetooth first. Every hifiberry-bluetooth up to 1.0.8 ships a prerm that
# rejects the deconfigure argument and exits 1, which aborts the transaction
# mid-unpack and leaves the system full of unpacked but unconfigured packages.
# dpkg runs the prerm of the *installed* version, so the archive cannot fix
# this for devices already below 1.0.6 -- upgrading the package on its own
# first is what stops dpkg ever having to deconfigure it. This has to happen
# before any apt upgrade step, not just before the full upgrade: a plain
# "apt upgrade" resolves Breaks by deconfiguring too.
