Failed to restore linux-arm

[ridomin]

Trying to build an image for raspberry

FROM mcr.microsoft.com/dotnet/sdk:6.0 AS build
WORKDIR /source
COPY . ./
RUN dotnet restore -r linux-arm
RUN dotnet publish -c release -o /app -r linux-arm --self-contained false --no-restore
FROM mcr.microsoft.com/dotnet/aspnet:6.0-bullseye-slim-arm32v7
WORKDIR /app
COPY --from=build /app ./

fails with

Very strange. I tried building the same Dockerfile you referenced and it works:

What type of environment are you running the build on? Can you provide the output of docker version and docker info? Also provide the command you are using to build this sample Dockerfile.
