I'm trying to install gcc-c++ on CentOS 7.6.1810. This is the error output:

Error: Package: glibc-2.17-260.el7.i686 (centos_7_x64_32)
   Requires: glibc-common = 2.17-260.el7
   Installed: glibc-common-2.17-260.el7_6.3.x86_64 (@updates)
       glibc-common = 2.17-260.el7_6.3
   (cut)
   Available: glibc-common-2.17-260.el7.x86_64 (centos_7_x64_32)
       glibc-common = 2.17-260.el7

It seems that yum doesn't recognize glibc-common-2.17-260.el7_6.3.x86_64 as the same as (or equivalent of) glibc-common-2.17-260.el7_6.3.x86_64. What can I do to tell it to honor this installed version, or how can I reinstall it from centos_7_x64_32 (obviously I can't remove glibc-common first).
