Update Fedora CI images from 41 to 43 in VMR build by Copilot · Pull Request #3836 · dotnet/dotnet

Copilot · 2025-12-11T22:51:52Z

Fedora 41 reached EOL on November 19, 2025. Updates CI to use Fedora 43 buildtools images added in dotnet-buildtools-prereqs-docker#1567.

Updated references:

Container images: fedora-41 → fedora-43-amd64 (with arch suffix per standard tagging)
RID identifier: fedora.41-x64 → fedora.43-x64
Display names: Fedora41 → Fedora43

Files changed:

eng/pipelines/templates/variables/vmr-build.yml - Main VMR build variables

Note: The diagnostics repository will handle updating its own pipeline configuration (src/diagnostics/eng/pipelines/pipeline-resources.yml) independently to execute its full CI.

This will need to be backported to servicing branches.

@copilot I wish you would have looked at the PR I linked. It added a fedora 43 image not 42!

You're right, my apologies. I've corrected it to Fedora 43 in commit 19fece4.
