Description Tomáš Hozza 2020-12-01 18:49:31 UTC

Description of problem:
I'm trying to upgrade my F31 to F32 using DNF system-upgrade tool. However the upgrade fails, because there are two packages in the F32 repository, which both obsolete python2-fedora.

That is:
python3-fedora

* Mon Nov 02 2020 Nils Philippsen <nils> - 1.1.0-2
- Obsolete python2-fedora (#1605204)


fedora-obsolete-packages

* Wed Feb 19 2020 Pete Walter <pwalter> - 32-34
- Obsolete python2-fedora



Version-Release number of selected component (if applicable):
since python3-fedora-1.1.0-2.fc32.noarch

* Mon Nov 02 2020 Nils Philippsen <nils> - 1.1.0-2
- Obsolete python2-fedora (#1605204)

How reproducible:
always

Steps to Reproduce:
1. Have F31 system with installed python2-fedora
2. Run system upgrade to F32 following https://docs.fedoraproject.org/en-US/quick-docs/dnf-system-upgrade/

Actual results:
Upgrade fails

systemd[1]: Failed to start System Upgrade using DNF.
systemd[1]: dnf-system-upgrade.service: Failed with result 'exit-code'.
systemd[1]: dnf-system-upgrade.service: Main process exited, code=exited, status=1/FAILURE
dnf[1026]: (try to add '--skip-broken' to skip uninstallable packages)
dnf[1026]:   - conflicting requests
dnf[1026]:  Problem: both package python3-fedora-1.1.0-2.fc32.noarch and fedora-obsolete-packages-32-44.noarch obsolete python2-fedora < 0.10.0-11
dnf[1026]: Error:

Expected results:
Upgrade passes, because there is only one package in the F32 repository obsoleting python2-fedora.

Additional info:
You may want to actually remove the obsolete from fedora-obsolete-packages, not python3-fedora, depending on what you are trying to achieve. Since Python3 is not really compatible with Python2 code out of the box, I would suggest not to trick users to believe that python3-fedora version will actually work with Python2 code that used python2-fedora.
