SkiaSharp3.116.1部署到Linux不工作，提示libSkiaSharp.so找不到的解决办法

问题：

项目在Windows下工作一切正常，发布Linux 64版本，部署到Ubuntu 24.04后，控制台看到错误提示：libSkiaSharp.so找不到。

解决方案：

Nuget安装下面的包即可解决，SkiaSharp.NativeAssets.Linux.NoDependecies

Visual studio 2019下操作路径：

菜单：工具-》Nuget包管理器-》管理解决方案的NuGet程序包

搜索SkiaSharp即可以看到，安装后，发布项目就会看到，已发布文件夹下有libSkiaSharp.so这个文件。

 

直接复制libSkiaSharp.so到已部署项目根目录使用也可以解决问题。

将.NET 升级到9.0.3后，出现以下问题：

fail: Microsoft.AspNetCore.Diagnostics.ExceptionHandlerMiddleware[1]
      An unhandled exception has occurred while executing the request.
      System.TypeInitializationException: The type initializer for 'SkiaSharp.SKAbstractManagedStream' threw an exception.
       ---> System.DllNotFoundException: Unable to load shared library 'libSkiaSharp' or one of its dependencies. In order to help diagnose loading problems, consider using a tool like strace. If you're using glibc, consider setting the LD_DEBUG environment variable:

      /usr/lib/dotnet/shared/Microsoft.NETCore.App/9.0.3/liblibSkiaSharp: cannot open shared object file: No such file or directory

解决办法：

sudo apt-get update
sudo apt-get install -y libfontconfig1 libfreetype6 libpng16-16 libjpeg-turbo8 libglib2.0-0

单安装libfongconfig1不能解决问题。干脆将依赖全安装了就好了。

复制libSkiaSharp.so到 /usr/lib/dotnet/shared/Microsoft.NETCore.App/9.0.3/libSkiaSharp.so，没有作用，不需要。后来好了以后，我删除了也一样不影响。
