Windows: unhelpful error message when pulling an up-level, multi-arch image #38199
Description
Repro steps:
- Install a pre-1809 version of Windows 10 (aka 1803), enable containers feature, etc.
- Install the latest docker client (must be new enough to have the fix for Windows: Block pulling uplevel images #36327).
- Attempt to pull a multi-arch 1809 image (where each of the sub-images is a blocked, up-level image)
- Try to make sense of the error message. :)
>docker pull mcr.microsoft.com/windows/nanoserver:1809
1809: Pulling from windows/nanoserver
no matching manifest for unknown in the manifest list entries
Ideally, in this case we'd display something like the excellent message you see if you try to pull one of the architecture-specific sub-images:
>docker pull mcr.microsoft.com/windows/nanoserver:1809_amd64
1809_amd64: Pulling from windows/nanoserver
a Windows version 10.0.17763-based image is incompatible with a 10.0.17134 host
