[ppc64le] NU1101 restore failure in BasicLinkedApp / LinkabilityChecker

[Swapnali911]

Description

The aspnetcore build fails on linux-ppc64le with NU1101 errors for Microsoft.NETCore.App.Runtime.linux-ppc64le and Microsoft.NETCore.App.Host.linux-ppc64le in two projects that use publish-with-link/trim scenarios. The issue occurs when building aspnetcore on linux-ppc64le with .NET SDK 11.0.100-preview.3.26207.106

Affected projects

src/Hosting/test/testassets/BasicLinkedApp/BasicLinkedApp.csproj
src/Tools/LinkabilityChecker/LinkabilityChecker.csproj

Triage Summary

Area: area-infrastructure — The failure occurs in build/test infrastructure projects (BasicLinkedApp and LinkabilityChecker) due to NU1101 NuGet restore errors for linux-ppc64le runtime packages. The packages Microsoft.NETCore.App.Runtime.linux-ppc64le and Microsoft.NETCore.App.Host.linux-ppc64le are absent from all configured NuGet feeds, indicating the build system / NuGet sources don't yet cover the linux-ppc64le architecture. This is a build infrastructure concern rather than any specific product feature area.

Type: bug — The build breaks reproducibly on linux-ppc64le with .NET SDK 11.0.100-preview.3.26207.106. The expected behavior is that restore succeeds on all supported platforms.

Regression Info

No explicit "used to work" version is mentioned. The reporter does not state that this ever worked on linux-ppc64le, so this may be a first-time enablement gap rather than a regression. The team may wish to confirm whether linux-ppc64le is an officially targeted platform for .NET 11.

Potential Duplicates

• None found

Notes

• The root cause is likely that linux-ppc64le runtime packs are not published to the standard dotnet NuGet feeds used by the aspnetcore build. A fix could involve: (a) adding linux-ppc64le runtime packs to the relevant feeds, (b) conditionaling out the publish/trim scenarios for unsupported RIDs, or (c) adding a RuntimeIdentifiers exclusion for unknown architectures in BasicLinkedApp.csproj / LinkabilityChecker.csproj.
• The base64-encoded source in the error (L3Jvb3QvamVua2lucy1zY3JpcHRzL2NpL2dycGMvYXJ0aWZhY3RzCg==) decodes to /root/jenkins-scripts/ci/grpc/artifacts, suggesting a local artifact feed that does not contain ppc64le packages either.
