Ah, I see. It would seem logical to me that any error in step 4 leads to
the error unwind procedure in step 5, substep 2, but I must admit it
isn't clearly written (you could think it can't be that because maybe
new-postrm wasn't even unpacked yet, but this is not a valid reason: as
you can see, new-postrm is already used in step 3, which shows dpkg
extracts it from control.tar.gz before it extracts the files from
data.tar.gz).
