centos 8: debuginfo-install can't find kernel-debuginfo package

Solution 1:

There are two ways of doing this. On CentOS 8,

1. You can modify /etc/yum.repos.d/CentOS-Debuginfo.repo to set enable=1 and then run yum install kernel-debuginfo or
2. You can do yum --enablerepo="base-debuginfo" install kernel-debuginfo

Either of these worked on my system. Be sure you have plenty of space on your disk. The installed size is 3.1GB.

NOTE :

1. You'll want to inspect the kernel version used in kernel-debuginfo (i.e. yum info kernel-debuginfo) to ensure that it is the same version as your kernel (i.e. uname -r).
2. If they differ, you may need to go hunting for the correct versions of kernel-debuginfo and kernel-debuginfo-common-x86_64. I used the baseurl in /etc/yum.repos.d/CentOS-Debuginfo.repo as a template to find where to look. For CentOS 8.1 look here.
