Alpine320_Online_MsftSdk_x64 (internal Microsoft link) tests also failed with the same issue:

@mthalman - what is the fix here? Does SB need to be re-bootstrapped?

[mthalman]

Looks like the wrong RID is being used. From the test output: publish --self-contained true -r linux-x64. It should be using linux-musl-x64 instead.

[mthalman]

I don't understand how this ever worked. It's always set the RID to linux-x64 even in past versions when this was working: https://github.com/dotnet/dotnet/blob/0d9fcc105f4c482ebde73e3b513053a53a9792a1/test/Microsoft.DotNet.SourceBuild.SmokeTests/TestScenario.cs#L62

[MichaelSimons]

Did it work because is was just publishing linux-x64 from an alpine alpine environment, it was not actually running the published application? Now something changes which bundles linker library with the app?

[mthalman]

It does run the application and always has in past .NET versions. It's really weird. I tried changing the RID to linux-musl-x64 and it worked. Interestingly, it also worked in the CentOS leg.
