Description Elliott Sales de Andrade 2019-05-11 09:01:27 UTC
Description of problem:
If python2-filelock is installed on Fedora 29, then upgrade generates no issues, but the transaction check fails due to conflicting files. Due to the manpage being in a common location, the F30 package needs to Conflict or Obsoletes the old python2-filelock version.


Version-Release number of selected component (if applicable):
python2-filelock-2.0.8-7.fc29.noarch -> python3-filelock-3.0.10-2.fc30.noarch 


Steps to Reproduce:
1. Install python2-filelock on F29
2. Attempt to upgrade to F30


Actual results:
Error: Transaction check error:
  file /usr/share/man/man1/py-filelock.1.gz from install of python3-filelock-3.0.10-2.fc30.noarch conflicts with file from package python2-filelock-2.0.8-7.fc29.noarch


Expected results:
Upgrade should work.

Adding Conflicts with the older version will just prevent you from installing the Fedora 30 Python 3 package, which is probably getting pulled in during your update for a reason. I doubt that will allow the update to proceed.

The problem here is that the python 2 package has been dropped, so it has no updated Fedora 30 package to roll to. You should uninstall the Python 2 package before updating, since it no longer exists in Fedora 30.

Yes, that's good, because you should not depend on implicit file conflicts:
https://docs.fedoraproject.org/en-US/packaging-guidelines/Conflicts/#_implicit_conflicts

Explicit Conflicts can be resolved with --allowerasing. That being said, you should request that Obsoletes be added to fedora-obsolete-packages (or to your own package if you prefer):

Yes, I know how to fix it; this report is about fixing it for others correctly.
