Description of problem: Python3-libs should not depend on /usr/bin/python3.6: ~~~ $ rpm -qR python3-libs ... snip ... /usr/bin/python3.6 ... snip ... ~~~ If this dependency is really required, then the split of -libs package makes no sense. Version-Release number of selected component (if applicable): $ rpm -q python3-libs python3-libs-3.6.4-1.fc28.x86_64 How reproducible: Steps to Reproduce: 1. 2. 3. Actual results: python3-libs depends on /usr/bin/python3.6 and therefore on python3 package. Expected results: python3-libs does not depend on python3 package Additional info:
On my Fedora 27, following files have the shebang that pulls the dependency: /usr/lib64/python3.6/base64.py /usr/lib64/python3.6/cProfile.py /usr/lib64/python3.6/cgi.py /usr/lib64/python3.6/encodings/rot_13.py /usr/lib64/python3.6/idlelib/pyshell.py /usr/lib64/python3.6/keyword.py /usr/lib64/python3.6/lib2to3/pgen2/token.py /usr/lib64/python3.6/pdb.py /usr/lib64/python3.6/platform.py /usr/lib64/python3.6/profile.py /usr/lib64/python3.6/quopri.py /usr/lib64/python3.6/smtpd.py /usr/lib64/python3.6/smtplib.py /usr/lib64/python3.6/symbol.py /usr/lib64/python3.6/tabnanny.py /usr/lib64/python3.6/tarfile.py /usr/lib64/python3.6/timeit.py /usr/lib64/python3.6/trace.py /usr/lib64/python3.6/uu.py /usr/lib64/python3.6/webbrowser.py Those files are executable and have a "main part" that gets run when executed. I however wonder how beneficial this actually is and how many users need to execute them.
I doubt anyone would call `/usr/lib64/python3.6/keyword.py` rather than `python3 -m keyword`. But, I guess that's an upstream issue (and earliest we can get it in there is 3.8). Should we only recommend /usr/bin/python3, instead of requiring it? That would make sense to me. Runnable scripts are not the main-purpose of python3-libs and the error message of missing python3 is nice and actionable. But, things stand, you do need python3 to get the full functionality.
Filtering the autogenerated "Requires: /usr/bin/python3.6" replacing it by Recommends makes sense to me.

Given the severity of this, I don't consider backporting to stable Fedoras necessary. Feel free to reopen if you disagree.
Thx for fixing this. The buildroot is slimmer by ~3 packages due to this change.
Do you know what pulls python3-libs into the buildroot and whether it works without python3?
It appears to be gdb-headless.
