I get this:
Checking for unpackaged file(s): /usr/lib/rpm/check-files
/builddir/build/BUILDROOT/glibc-2.26-1.fc27.1.i386
error: Installed (but unpackaged) file(s) found:
/usr/lib/locale/aa_DJ.utf8/LC_ADDRESS
…
This also happens with a version which built previously. It appears to
be caused by RPM changes which result in an empty list of langpack packages.
I'm trying to fix this.
