Hello, Please note that this comment was generated automatically by https://forge.fedoraproject.org/releng/tooling/src/branch/main/release-process/bug-filing/follow-policy/follow_policy.py If you feel that this output has mistakes, please open an issue at https://forge.fedoraproject.org/releng/tickets/issues Your package (blender) Fails To Install in Fedora 42: can't install blender: - nothing provides liboslquery.so.1.13()(64bit) needed by blender-1:4.5.6-2.fc42.x86_64 - nothing provides liboslcomp.so.1.13()(64bit) needed by blender-1:4.5.6-2.fc42.x86_64 - nothing provides liboslexec.so.1.13()(64bit) needed by blender-1:4.5.6-2.fc42.x86_64 If you know about this problem and are planning on fixing it, please acknowledge so by setting the bug status to ASSIGNED. If you don't have time to maintain this package, consider orphaning it, so maintainers of dependent packages realize the problem. If you don't react accordingly to the policy for FTBFS/FTI bugs (https://docs.fedoraproject.org/en-US/fesco/Fails_to_build_from_source_Fails_to_install/), your package may be orphaned in 8+ weeks. P.S. The data was generated solely from koji buildroot, so it might be newer than the latest compose or the content on mirrors. To reproduce, use the koji/local repo only, e.g. in mock: $ mock -r fedora-42-x86_64 --config-opts mirrored=False install blender P.P.S. If this bug has been reported in the middle of upgrading multiple dependent packages, please consider using side tags: https://docs.fedoraproject.org/en-US/fesco/Updates_Policy/#updating-inter-dependent-packages Thanks!
These libraries are provided by the OpenShadingLanguage (OSL) package. This FTI error means that the OpenShadingLanguage package in Fedora 42 was recently updated to a newer version (which bumped the library soname, e.g., to 1.14 or higher). Because current Blender package was compiled against OSL 1.13, it is now broken in the Fedora 42 buildroot.
Just noting that such ABI- or API-breaking updates in stable releases are prohibited by the updates policy, https://docs.fedoraproject.org/en-US/fesco/Updates_Policy/#stable-releases, even if the necessary rebuilds are coordinated. Linking the update in question: https://bodhi.fedoraproject.org/updates/FEDORA-2026-7cc03013be At this point, since the update has reached stable, rebuilding the affected packages in F42 is probably the most reasonable way forward. That should just be usd and blender, since materialx was included in the original update. I’ll attempt this.
It is strange. Osl 1.14 is there for a really long time. Why it is complaining now? We didn't touch osl version. https://src.fedoraproject.org/rpms/openshadinglanguage/history/openshadinglanguage.spec?identifier=f42

The last build of openshadinglanguage for F42 before the breaking update was openshadinglanguage-1.13.12.0-4.fc42, shipped in https://bodhi.fedoraproject.org/updates/FEDORA-2025-48b7f3a71d. Looking at the update history https://bodhi.fedoraproject.org/updates/?packages=openshadinglanguage is a better guide to what has actually reached the repos.
I’m going to run through usd and blender rebuilds locally in mock to make sure this is going to work, then I’ll start real builds in a side tag.
Thank you Ben.
