I need to obsolete one of the arch subpackages in the cross-binutils rpm (and also in the cross-gcc rpm) because binutils no longer supports that arch (sh64). Just marking the appropriate subpackage as obsoleted in the specfile for the cross-binutils-common subpackage causes dnf to complain: warthog>sudo dnf upgrade ./noarch/cross-binutils-common-2.27-1.fc26.noarch.rpm ./x86_64/binutils-* Last metadata expiration check: 0:20:38 ago on Wed Sep 14 15:06:27 2016. Error: package binutils-sh64-linux-gnu-2.26.1-1.fc24.x86_64 requires cross-binutils-common = 2.26.1-1.fc24, but none of the providers can be installed (try to add '--allowerasing' to command line to replace conflicting packages) Is this the right way to do things?
