Please see the devel list thread for more info. There are a few issues that need to be ironed out:

• if the requested memory is too high, the macro may result in 0 threads effectively breaking: this should not occur. It should at least give 1 thread.
• the way the macro is written also seems to cause issues with using %{?_smp_build_ncpus} in %if conditionals: the spec file does not parse at all
• it is also undocumented that this must be used in the %build section of the spec, otherwise the spec won't parse either.

Giving negative karma to prevent it from going stable automatically.

Also cannot be installed because it needs specific versions of numpy and h5py. Negative karma to prevent pushing to users.

Same here:

Problem: cannot install the best update candidate for package OpenImageIO-2.2.10.0-1.fc33.x86_64
  - nothing provides libopenvdb.so.8.0()(64bit) needed by OpenImageIO-2.2.11.1-1.fc33.x86_64

Same here:

Problem: package libabigail-fedora-1.7-2.fc33.x86_64 requires libabigail(x86-64) = 1.7-2.fc33, but none of the providers can be installed

  - cannot install the best update candidate for package libabigail-1.7-2.fc33.x86_64

Very odd. This isn't working for me at all here:

$ rpm -q podman containers-common
podman-2.2.0-2.fc33.x86_64
containers-common-1.2.0-10.fc33.x86_64

$ podman run -it fedora:33 /bin/bash
Error: container_linux.go:349: starting container process caused "error adding seccomp rule for syscall socket: permission denied": OCI permission denied

Downgrading packages fixes it:

$ rpm -q podman containers-common
podman-2.1.1-12.fc33.x86_64
containers-common-1.2.0-3.fc33.x86_64

$ podman run -it fedora:33 /bin/bash
[root@48ef5add7d53 /]# exit

Also seeing this issue, even with --allowerasing:

This makes python-pynwb uninstallable on Fedora 32. It should not be pushed to stable until a version of pywnb that can use this new version is available:
