Package: aspcud,aptitude
severity: important

When trying to build node-buble (and any other package that build 
depends on node-acorn provided as a virtual package by 
node-debbundle-acorn in buster-backports)

(I)Distcheck: Cudf Universe: 61258 packages
(I)Distcheck: --checkonly specified, consider all packages as 
background packages
(I)Distcheck: Solving...
output-version: 1.2

      version: 0.invalid.0
      architecture: amd64
      unsat-dependency: node-acorn:amd64 (>= 6~) | node-acorn:amd64 (>= 

node-buble says node-acorn (>= 6~) in Build-Depends

and node-debbundle-acorn in buster-backports provides
node-acorn (= 8.0.4+ds+~cs19.19.27-1)

and node-acorn real package version in buster is 5.5.3+ds3-3

Build command used is,

sbuild -A -s --force-orig-source -c buster-amd64-sbuild 
--extra-repository='deb http://deb.debian.org/debian buster-backports 
main' --extra-repository='deb http://incoming.debian.org/debian-buildd 
buildd-buster-backports main' --build-dep-resolver=aptitude 

fails for both aptitude and aspcud
