dpatch 2.0.38 (arm64 binary) in ubuntu bionic

 dpatch is an easy to use patch system for Debian packages, somewhat
 similar to the dbs package, but much simpler to use.
 .
 It lets you store patches and other simple customization templates in
 debian/patches and otherwise does not require much reorganization of
 your source tree. To get the patches applied at build time you simply
 need to include a makefile snippet and then depend on the
 patch/unpatch target in the build or clean stage of debian/rules - or
 you can use the dpatch patching script directly.
 .
 It can easily apply patches only on specific architectures if needed.
