You're faced with a relatively early dumat-generated report and I see
how the lack of detail makes diagnosing this difficult. Later reports
have been improved to include the missing detail.

Let me paste the machine-readable report and explain it.

Specifically, you need a version of libsequoia-octopus-librnp from
unstable or experimental and combine it with a thunderbird version from
bullseye, bookworm or experimental. If we disregard experimental and
assume that libsequoia-octopus-librnp to trixe, apt could choose to
first install libsequoia-octopus-librnp in a bookworm to trixie upgrade
before upgrading thunderbird to drop the file.

So to reproduce this, I recommend using a bookworm system, install
thunderbird, add unstable to apt sources, install
libsequoia-octopus-librnp.
