$ sudo dnf upgrade --enablerepo={fedora,updates}-debuginfo glibc-debuginfo glibc-debuginfo-common
(same)

$ rpm -qa |grep glibc-debug|sort
glibc-debuginfo-2.30-5.fc31.i686
glibc-debuginfo-2.30-5.fc31.x86_64
glibc-debuginfo-common-2.30-5.fc31.x86_64

After I remove glibc-debuginfo-2.30-5.fc31.i686, I can update the x86_64 version of the package.

Ideally, the two arch versions would be parallel installable. But if they can't, they should Conflict, so that dnf handles this better.
