libghc-conduit-extra-dev binary package in Ubuntu Focal riscv64

 The conduit package itself maintains relative small dependencies. The
 purpose of this package is to collect commonly used utility functions
 wrapping other library dependencies, without depending on
 heavier-weight dependencies. The basic idea is that this package
 should only depend on haskell-platform packages and conduit.
 .
 This package provides a library for the Haskell programming language.
 See http://www.haskell.org/ for more information on Haskell.
