I did notice this issue with the build, but wasn't sure how to
approach it. It's not exactly clear to me why Ubuntu Focal would have
difficulties installing 'libboost-signals1.67-dev' on a fresh image. I
would need to test a few things just to understand why this is
happening.

Unfortunately these days available time is very limited, and I don't
have handy access to a Focal system either, so debugging this will
likely take a few weeks. If someone has an idea why this issue is
occurring on Focal (and how to fix it), please contact me off-list.
