Description Aoife Moloney 2026-07-21 15:40:26 UTC 
This is a tracking bug for Change: Disable Vendor Change by Default
For more details, see: https://fedoraproject.org/wiki/Changes/DisableVendorChangeByDefault

Change the default configuration of DNF5/libdnf5 by setting allow_vendor_change=False via the distribution defaults file /usr/share/dnf5/libdnf.conf.d/20-fedora-defaults.conf. This prevents libdnf5 from automatically replacing an installed package from one vendor with a package from another vendor during any transaction (such as upgrades, downgrades, or dependency resolution), unless explicitly requested by the user or allowed by VendorChangeManager rules.

If you encounter a bug related to this Change, please do not comment here. Instead create a new bug and set it to block this bug.
Comment 1 Aoife Moloney 2026-08-31 11:07:59 UTC 
Hi Jaroslav, is this change complete for F45? Or do you need to retarget to F46?
Comment 2 Neal Gompa 2026-09-01 15:47:03 UTC 
It looks like this was pending for months and merged by fedora-release late: https://src.fedoraproject.org/rpms/fedora-release/c/241c45dac896cbd39bb52a4b64e1de317ab02640?branch=rawhide

fedora-release people need to cherry-pick it back into F45.
Comment 3 Neal Gompa 2026-09-04 01:52:27 UTC 
This is now pending on this update landing: https://bodhi.fedoraproject.org/updates/FEDORA-2026-0efcf88ca2
Comment 4 Adam Williamson (Fedora) 2026-09-04 19:22:25 UTC 
I don't think it's a good idea to land this so late. See https://bugzilla.redhat.com/show_bug.cgi?id=2528348#c3 . I think it should be deferred to F46.
Comment 5 Neal Gompa 2026-09-08 18:21:51 UTC 
I'm not sure what happened here, because it looks like it was merged August 10, and built as fedora-release-45-0.9... But it only made it into rawhide and not the f45 tag despite happening before branching.

I mean the original commit: https://src.fedoraproject.org/rpms/fedora-release/c/241c45dac896cbd39bb52a4b64e1de317ab02640

https://forge.fedoraproject.org/fesco/tickets/issues/3682#issuecomment-1355057

"AGREED: This Change is retargeted to Fedora 46 (+5, 0, -2)"

Deferring to F46.
Comment 8 Adam Williamson (Fedora) 2026-09-10 16:03:38 UTC 
This has been in Rawhide since https://bodhi.fedoraproject.org/updates/FEDORA-2026-48def1df6c , so marking as ON_QA.
