我写了一个Dockerfile使用 Docker buildx--mount=type=cache设置缓存我的 NuGet 包以加快构建速度。正如所示，这似乎在 .NET 5 中有效其他问题 https://stackoverflow.com/questions/69464184/using-docker-buildkit-mount-type-cache-for-caching-nuget-packages-for-net-5-d.
FROM mcr.microsoft.com/dotnet/sdk:6.0 AS sdk
WORKDIR /src
COPY "ApiTemplate.sln" "."
COPY "Source/ApiTemplate/*.csproj" "Source/ApiTemplate/"
# Run the restore and cache the packages on the host for faster subsequent builds.
RUN --mount=type=cache,id=nuget,target=/root/.nuget/packages \
dotnet restore
COPY . .
RUN dotnet build --configuration Release --no-restore
...
但是，在 .NET 6 中我收到以下错误：
=> [linux/amd64 sdk 6/10] RUN --mount=type=cache,id=nuget2,target=/root/.nuget/packages dotnet restore 20.9s
=> CANCELED [linux/arm64 sdk 6/10] RUN --mount=type=cache,id=nuget2,target=/root/.nuget/packages dotnet restore 23.0s

似乎是dotnet restore失败。这个问题的解决办法是什么？
