Occurring with:
2019.1.14f1, 2019.2.0a13, 2019.2.1f1, 2019.3.0a12

Working with:
2019.3.0a2, 2019.2.0a12

Windows Only

Stack Trace:
Copying assembly from 'Temp/com.unity.multiplayer-hlapi.Runtime.dll' to 'Library/ScriptAssemblies/com.unity.multiplayer-hlapi.Runtime.dll' failed

  1. Resolution Note (fix version 1.0.6):

    Closing since UNet is deprecated and this seems like low priority issue. It should only happen once and only when upgrading older projects in 2019.x. Package is automatically added in this upgrade flow, this will no longer happen in 2020.1. It's safe to remove from the manifest or package manager if it's not being used. Reopening editor should also get rid of the issue. If it's still a problem it can be worked around by embedding the package and editing WeaverRunner.cs OnCompilationFinished function, adding this at the top:
    if (targetAssembly.StartsWith(“Unity”))

    , remove the file
    and now build works again, once only. The file-removal procedure has to be repeated for every build
