VMR Build Failure: Package Not Found: microsoft.netcore.app.crossgen2.linux-x64

[mmitche]

Failure Mode: Package Not Found – microsoft.netcore.app.crossgen2.linux-x64

Detailed Explanation

The build is failing because it cannot find the required NuGet package microsoft.netcore.app.crossgen2.linux-x64 at the specified version. This typically occurs when the requested package version does not exist in any of the configured feeds, or the feeds are not up-to-date. The error is consistently observed in both CentOS and Alpine container jobs, resulting in a bash exit code 1.

Relevant error lines:

• error NU1102: ... Unable to find package microsoft.netcore.app.crossgen2.linux-x64 with version (= ...)
• Bash exited with code '1'.

Locations within a build:

• CentOSStream9_Online_PreviousSourceBuiltSdk_x64 (Build (centOSStreamContainer))
• Alpine321_Offline_MsftSdk_x64 (Build (alpineContainer))
