Sure. The Build-Depends are not installable. I cannot even start
building and you seem to have figured that much.

Annotating python3 with :any is the right thing to do. The :all
annotation is not valid unfortunately. You are now suffering the famous
"multi-arch interpreter problem" with the new python3-ply dependency. I
have little options to fix. In theory, annotating it :native could work,
but dpkg disagrees with apt and dose on what that is supposed to mean,
so that doesn't work in practise (see #854438). Then we could apply the
"multi-arch interpreter workaround" to python3-ply, which means turning
python3-ply Architecture: any. This workaround is not universally liked.
I'm sorry, I don't have any good options now. This doesn't look fixable
with reasonable effort to me.
