I maintain numerous python packages, so I thought I give one a shot at singlespec:

https://build.opensuse.org/package/show/home:gregfreemyer:Tools-for-forensic...

The build is failing, even for factory which should have all the needed dependencies. It says the failure is temporary, but it has been over 12 hours and I suspect the problem is with my spec file.

Anyone know what I'm doing wrong?

You can see in the log the python2 build works:

But the python3 build fails: ===

It looks like pbr is a build requirement for both python2 and python3, but you only BuildRequires the python2 version. Since the python3 version of pbr cannot be found, setuptools is trying to download it, but can't because the OBS sandbox prevents downloading files. This leads to your error.

To fix this, the line:

BuildRequires: python-pbr

should be

BuildRequires: %{python_module pbr}

Overall, "BuildRequires: python-foo" should only be used when the python2 version of the package Buildrequires "python-foo" but the python3 version does not BuildRequires "python3-foo" (and vice versus, but that is rarer except for python3-Sphinx).

Note that you don't need to do this for Requires, "python-foo" will be automatically converted to the appropriate package for Requires.

On another note, it doesn't look like this package follows python package naming guidelines. This is based on the "bencode.py" project [1], rather than the "bencode" project [2]. So it should be "python-bencode.py", which should Provides/Obsoletes python-bencode. For Provides/Obsoletes, it should be Provides/Obsoletes "python-bencode" as well as "%{oldpython}-bencode". See the the wiki page for more details [3].
