Broken debian package for stable: "bullseye"

When trying to upgrade to siegfried v1.0.0-1, I'm seeing the following error:

paul@celebrimbor:~$ sudo apt-get upgrade

The above exception was the direct cause of the following exception:

Here is what seems to be a related issue on stack exchange.

In the stack exchange discussion, their problem is identified as the package being built with a newer version of dpkg (>= 1.21.18), which includes support this new compression.

I can confirm that my version of dpkg is older, so doesn't support this compression.

paul@celebrimbor:~$ dpkg-query -W dpkg
dpkg    1.20.12

Moreover, I'm running the current stable version of Debian, "bullseye":

paul@celebrimbor:~$ lsb_release -a
No LSB modules are available.
Distributor ID: Debian
Description:    Debian GNU/Linux 11 (bullseye)
Release:        11
Codename:       bullseye
