| Description | I have Rocky Linux 8.7 with kernel-debuginfo-4.18.0-425.3.1.el8.cloud.x86_64.
For crash utility, I tried to install kernel-debuginfo. But I got kernel-debuginfo-4.18.0-425.3.1.el8, not cloud version.
So I download kernel-debuginfo-4.18.0-425.3.1.el8.cloud.x86_64.rpm, and then do this:
# dnf install kernel-debuginfo-4.18.0-425.3.1.el8.cloud.x86_64.rpm
#dnf install kernel-debuginfo-4.18.0-425.3.1.el8.cloud.x86_64.rpm

Error:
Problem: conflicting requests
- nothing provides kernel-debuginfo-common-x86_64 = 4.18.0-425.3.1.el8.cloud needed by kernel-debuginfo-4.18.0-425.3.1.el8.cloud.x86_64
(try to add '--skip-broken' to skip uninstallable packages or '--nobest' to use not only best candidate packages)
I couldn't find matched could version, kernel-debuginfo-common-4.18.0-425.3.1.el8.cloud.x86_64 from cloud-kernel repo.
How to install kernel-debuginfo-4.18.0-425.3.1.el8.cloud.x86_64 properly. I would expect I have this after correct version installation:
/usr/lib/debug/lib/modules/4.18.0-425.3.1.el8.cloud.x86_64/vmlinux
and then I would run crash utility like that:
# crash /usr/lib/debug/lib/modules/4.18.0-425.3.1.el8.cloud.x86_64/vmlinux /var/crash/127.0.0.1-2022-12-13-01\:21\:41/vmcore
But if I install non-cloud version, kernel-debuginfo-4.18.0-425.3.1.el8.x86_64, I will get an error: (due to version is not matched between vmlinux and vmcore)
# crash /usr/lib/debug/lib/modules/4.18.0-425.3.1.el8.x86_64/vmlinux /var/crash/127.0.0.1-2022-12-13-01\:21\:41/vmcore
crash 7.3.2-2.el8
