I also was able to reproduce the error in a buster chroot (at first
try).  I was thinking whether --no-parallel might have helped as well
since this is a usual cause for non-predictable racing conditions.

I actually succeeded with


diff --git a/debian/rules b/debian/rules

Seems your fix goes more to the root of the issue so we should go
with this.

Yes, please do so.

Probably.
 
Kind regards
