Description Tomas Orsava 2021-08-05 11:15:05 UTC
Description of problem:
When upgrading from RHEL 8 to RHEL 9 using LEAPP, the upgrade fails if python39 packages were installed on the RHEL 8 system. The error says:

      file /usr/lib/python3.9/site-packages/__pycache__/six.cpython-39.opt-1.pyc from install of python3-six-1.15.0-6.el9.noarch conflicts with file from package python39-six-1.15.0-3.module+el8.4.0+9822+20bf1249.noarch
      <snip>

Full errer logfile attached.


How reproducible:
Every time


Steps to Reproduce:
1. Upgrade RHEL 8 to RHEL 9 using LEAPP, for example using this vagrant box: https://gitlab.cee.redhat.com/leapp/oamg-rhel8-vagrant


Actual results:
      file /usr/lib/python3.9/site-packages/__pycache__/six.cpython-39.opt-1.pyc from install of python3-six-1.15.0-6.el9.noarch conflicts with file from package python39-six-1.15.0-3.module+el8.4.0+9822+20bf1249.noarch
      <snip>

Full errer logfile attached.


Expected results:
System upgraded successfully

Comment 2 Miro Hrončok 2021-08-05 11:27:11 UTC
The python3-foo packages could automatically obsolete python39-foo packages. All we need is to adapt the https://gitlab.com/redhat/centos-stream/rpms/python-rpm-generators/-/blob/c9s/pythonname.attr generator to also have a %__pythonname_obsoletes macro. usual technical limits apply: packages without files and packages that have been renamed will need to maintain manual Obsoletes.

Indeed, that's one possible solution.

Another possibility is that when we add definitions into the Package Evolution Service (PES) that python39-foo in RHEL 8 is named python3-foo in RHEL 9, LEAPP will correctly deal with the packages.

We can implement both solutions to be sure.

This looks like it's the best way to go. We should discuss on python-devel in Fedora.

While testing this solution, I've found a bug in LEAPP: https://issues.redhat.com/browse/OAMG-6084

LEAPP have a working patch that solves the bug and in effect resolves this upgrade problem.

In the meantime, in Fedora I'm verifying a second solution that automatically generates Obsoletes tags, if it works, I'll implement it in RHEL 9 as well.
