Specifically, it was too old to recognize RISC-V as an architecture. So was the RISC-V architecture added to the ubuntu build between the uploads of the previous version of xfsprogs and xfsprogs-5.10.0? Or is this an actual regression where the maintainer signed tarball had RISC-V support in it and now it doesn't? FWIW, where are you getting the tarballs from? Are you downloading the maintainer signed tarballs from here: https://mirrors.edge.kernel.org/pub/linux/utils/fs/xfs/xfsprogs/ Or pulling the git.kernel.org built tarball that is autogenerated from the release tag? > >> @echo "== dpkg-buildpackage: configure" 1>&2 > >> $(checkdir) > >> AUTOHEADER=/bin/true dh_autoreconf > >> + dh_update_autotools_config > >> $(options) $(MAKE) $(PMAKEFLAGS) include/platform_defs.h > > > >Why would running at tool that does a search-n-replace of built > >config.guess files do anything when run before the build runs > >libtoolize to copy in the config.guess file it uses?

That sounds wrong. AIUI, autoreconf doesn't copy in anything. $ man 7 dh-autoreconf .... CAVEATS dh_autoreconf is mostly a superset of the dh_update_autotools_config debhelper command included in debhelper since version 9.20160115. When using the dh sequencer, dh_update_autotools_config is run before dh_autoreconf and updates the config.guess and config.sub files. This is required in cases where autoreconf does not update config.guess and config.sub itself. So isn't the dh_update_autotools_config call in the wrong place here?
