xiota [1] filed a deletion request for ddupes [2]: Upstream project abandoned 14 years ago. Never updated beyond Python 2. Unable to find any forks. Can no longer build for Python 3 because 2to3 has been removed. Cannot use python-fissix because it produces syntax errors. Although pkgstats shows some recent installs, it is past time to retire this package. [1] https://aur.archlinux.org/account/xiota/ [2] https://aur.archlinux.org/pkgbase/ddupes/
