Description Florian Weimer 2022-06-14 20:11:21 UTC 
# rpm -q annobin-docs --provides
annobin = 10.75-3.el9
annobin-docs = 10.75-3.el9

The problem with that is that if RPM selects annobin-docs to satisfy the glibc 

https://kojihub.stream.centos.org/koji/taskinfo?taskID=1208735

What complicates matters is that annobin-10.75-3.el9 is not a build off the c9s branch, it's a build made using the the scl-gcc-toolset-12-rhel-9.1.0 branch which was accidentally built against the c9s-candidate target (not the SCL target):

https://kojihub.stream.centos.org/koji/taskinfo?taskID=1203159

Its spec file contains the faulty Provides:

%package docs
Summary: Documentation and shell scripts for use with annobin
BuildArch: noarch
# annobin renamed to annobin-doc in 9.66-1
Provides:  %{name} = %{version}-%{release}
Obsoletes: %{name} < %{version}-%{release}
# The documentation uses pod2man...
BuildRequires: perl-interpreter perl-podlators gawk make sharutils
Comment 1 Florian Weimer 2022-06-14 20:26:20 UTC 
Curiously, this does not cause all builds to fail. Something seems to be special about the glibc build. lua rebuilds fine (otherwise the build would not have passed gating).
Comment 4 Florian Weimer 2022-06-15 05:26:43 UTC 
The glibc build fails because it assumes the plugin has the name annobin, not gcc-anobin. It is necessary to disable the plugin for the non-shared bits, and the way this is done today needs to know the exact plug-in name.
Comment 8 Nick Clifton 2022-06-24 10:39:03 UTC 
The gcc-toolset-12-annobin-10.76-2.el9 build does not fix the problem, but it does mitigate it:

  % rpm -q --provides -p gcc-toolset-12-annobin-docs-10.76-2.el9.noarch.rpm 
  gcc-toolset-12-annobin-docs = 10.76-2.el9
  gcc-toolset-12-gcc-toolset-12-annobin = 10.76-2.el9
  scl-package(gcc-toolset-12)

Since nothing should ever require a subpackage called gcc-toolset-12-gcc-toolset-12-annobin, the problem should not surface.

Obviously this is not the correct solution to the problem.  The next update to GTS-12 annobin, if it happens, should solve the problem by removing the Provides altogether.
