Docker Linux Container (Debain) - invalid ELF header

[imahruf]

Hi

I am getting below error message, anyone knows how to resolve it? I've read other threads but no luck.

System.DllNotFoundException: Unable to load shared library '/app/libwkhtmltox.dll' or one of its dependencies. In order to help diagnose loading problems, consider setting the LD_DEBUG environment variable: /app/libwkhtmltox.dll: invalid ELF header
   at System.Runtime.Loader.AssemblyLoadContext.InternalLoadUnmanagedDllFromPath(String unmanagedDllPath)

Below is my Dockerfile,

FROM mcr.microsoft.com/dotnet/core/sdk:2.1 AS build-env
WORKDIR /app

# Copy csproj and restore as distinct layers
COPY ./ABC/ABC.csproj ./
RUN dotnet restore

# Copy everything else and build
COPY ./ABC/. ./
RUN dotnet publish ABC.csproj -c Release -o out

# Build runtime image
FROM microsoft/dotnet:aspnetcore-runtime
WORKDIR /app
COPY --from=build-env /app/out .
