遇到Ubuntu致命错误.库'libhostpolicy.so'需要

Question

我对Ubuntu很新.我一直试图通过dotnet运行一个dll,但每次启动时都会遇到"遇到致命错误.在'/ root/duo /'中找不到执行应用程序所需的库'libhostpolicy.so'.

我做了一个

 sudo updatedb && locate hostpolicy.so | xargs sha1sum

得到了:

 1c51298979874c5ff0e30798406760c77bea7adc  /root/sdk/1.0.4/libhostpolicy.so

发生了什么,如何解决它并指向所述目录.我是否有任何冲突,因为我之前有一个我必须解决的dotnet问题？
