Docker - open /var/lib/docker/overlay2/xxx/merged/etc/passwd: no such file or directory

I'm trying to 'docker build -t aspnetapp .' But it stopped and shows error below.

=> ERROR [base 2/2] WORKDIR /app                                                                                                                                                                            ------

What I have tried:

Nothing works. Anyone has an idea to make this work?

Below is my Dockerfile

FROM mcr.microsoft.com/dotnet/core/aspnet:3.1-nanoserver-1903 AS base
WORKDIR /app
EXPOSE 80
EXPOSE 443

FROM mcr.microsoft.com/dotnet/core/sdk:3.1-nanoserver-1903 AS build
WORKDIR /src
COPY ["SampleCoreProject.csproj", "SampleCoreProject/"]
RUN dotnet restore "SampleCoreProject.csproj"
COPY . .
WORKDIR "/src/SampleCoreProject"
RUN dotnet build "SampleCoreProject.csproj" -c Release -o /app/build

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

FROM base AS final
WORKDIR /app
COPY --from=publish /app/publish .
ENTRYPOINT ["dotnet", "SampleCoreProject.dll"]

I create a new project which the .csproj and Dockerfile are at same folder, and the Dockerfile is a little different from yours, try this:

FROM mcr.microsoft.com/dotnet/aspnet:3.1 AS base
WORKDIR /app
EXPOSE 80
EXPOSE 443

FROM mcr.microsoft.com/dotnet/sdk:3.1 AS build
WORKDIR /src
COPY ["SampleCoreProject.csproj", "."]
RUN dotnet restore "./SampleCoreProject.csproj"
COPY . .
WORKDIR "/src/."
RUN dotnet build "SampleCoreProject.csproj" -c Release -o /app/build

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

FROM base AS final
WORKDIR /app
COPY --from=publish /app/publish .
ENTRYPOINT ["dotnet", "SampleCoreProject.dll"]
