Potential off-by-one in versions for runtime packs/app hosts/etc for .NET 7 vs .NET 6?

While investigating dotnet/sdk#39544 I discovered that the .NET 6 Ubuntu package and the .NET 7 Ubuntu package disagree about what the latest version of the .NET 6 Runtime Packs, AppHosts, etc should be. This means that the .NET 7 SDK cannot build a .NET 6 application without going to NuGet.org to download additional assets. This feels like a bug to me.

Repro Steps:

The dotnet6 package is version 6.0.127-0ubuntu1~22.04.1.
The dotnet7 package is version 7.0.117-0ubuntu1~22.04.1.

Here are the versions and names of the Packs required for a .NET 6 console application:

Pack Name .NET 6 SDK Installed Version .NET 7 SDK Installed Version .NET 7 Required Version for a .NET 6 app
Microsoft.NETCore.App.Ref 6.0.27 7.0.17 6.0.28
Microsoft.AspNetCore.App.Ref 6.0.27 7.0.17 6.0.28
Microsoft.NETCore.App.Host.linux-x64 - - 6.0.28
Microsoft.NETCore.App.Host.ubuntu-x64 6.0.27 7.0.17 -

Note here also that the 7 SDK is looking for a specific AppHost RID that is not being installed, which also causes an errant download, but that's a separate issue.

This may be a point in time problem - the 7 SDK on the distro feeds matches to the latest release (7.0.17 from 3 days ago) but the 6 SDK on the distro feeds is one behind (6.0.28 from 3 days ago) - maybe that's the whole problem?

@MichaelSimons seems like there was a delay in the distro built 6 version of the SDK. Additionally, it sounds like something with their source build version is creating a need for an unbuntu app host. I'm not sure if that's expected. Maybe a topic for the next source build meeting with our OSS partners.

source-build are RID specific, they are not portable.
