dockerfile 中的 RUN 命令未执行

Question

我正在使用带有 Docker 的 Visual Studio 2019 构建 dotnet5 API，以部署在 Linux 映像中。我需要向生成的 docker 映像添加一些本机依赖项，​​因此我在 dockerfile 中触发 app-get 命令：

FROM mcr.microsoft.com/dotnet/aspnet:5.0 AS base
WORKDIR /app
EXPOSE 80
EXPOSE 443

FROM mcr.microsoft.com/dotnet/sdk:5.0 AS build
WORKDIR /src
COPY ["CourtBooking/CourtBooking.csproj", "CourtBooking/"]
RUN dotnet restore "CourtBooking/CourtBooking.csproj"
COPY . .
WORKDIR "/src/CourtBooking"
RUN dotnet build "CourtBooking.csproj" -c Release -o /app/build

FROM build AS publish
RUN dotnet publish "CourtBooking.csproj" -c Release -o /app/publish

FROM base AS final
WORKDIR /app
COPY --from=publish /app/publish .
RUN apt-get update \
    && apt-get install -y --allow-unauthenticated \
        libc6-dev \
        libgdiplus \
        libx11-dev \
     && rm -rf /var/lib/apt/lists/*
ENTRYPOINT ["dotnet", "CourtBooking.dll"]

然而，apt-get 永远不会运行，这是我构建的输出：

我正在 Win10 PRO v 20H2 上构建解决方案，使用 WSL2 Debian Linux XXX 5.4.72-microsoft-standard-WSL2 #1 SMP Wed Oct 28 23:40:43 UTC 2020 x86_64 GNU/Linux

相同的 dockerfile 在 Linux 机器上正确执行。有关如何解决此问题的任何提示？
