Installation fails during postinstall in lava-docker

During the setup of lava-docker 2026.04 with mtda the installation fails with the following error:

You will have to specify in more details how you are installing the binary package.

FWIW, following https://mtda.readthedocs.io/en/latest/install.html#using-apt-on-debian-13 in a trixie container Just Works (TM). There must be another variable that breaks things.

Setting up python3-zope.event (5.0-0.1) ...
Setting up python3-zope.interface (7.2-1+b1) ...
Setting up python3-gevent (24.11.1-1+b1) ...
Setting up mtda-systemd-helper (0.47-1) ...
Created symlink '/etc/systemd/system/multi-user.target.wants/mtda-systemd-helper.path' → '/usr/lib/systemd/system/mtda-systemd-helper.path'.
Created symlink '/etc/systemd/system/multi-user.target.wants/mtda-systemd-helper.service' → '/usr/lib/systemd/system/mtda-systemd-helper.service'.
Setting up python3-botocore (1.37.9+repack-1) ...
Setting up python3-s3transfer (0.11.4-1) ...
Setting up python3-boto3 (1.37.9-1) ...
Setting up mtda-client (0.47-1) ...
Setting up dmsetup (2:1.02.205-2) ...

Interestingly, the setup ordering between mtda-systemd-helper and mtda-client is different in my case.

My fault i used https://apt.fury.io/mtda instead of https://apt.fury.io/mtda-trixie as package feed.
