@wheelcomplex Thanks for the report! Looks like CoreCLR removed its dependency on libcurl3, libunwind8 and libuuid1 for .NET Core 2.1, but the debugger is still running on .NET Core 2.0 (and has its own dependency on the later two in addition). Before we would get our dependencies resolved 'for free'. But on boxes with only .NET Core 2.1, that will no longer be the case.

Please continue to work around the issue while we figure out what to do.
