当我运行一个脚本来停止两个服务时，我的 Ubuntu 16.4 LTS 崩溃了。经过谷歌搜索，我发现我的系统中有很多 Linux 镜像。默认情况下它使用
linux-image-4.4.0-187-generic
我将其改为
linux-image-4.4.0-185-generic
在启动过程中高级选项。
现在，系统正常，但每当我重新启动时，它就会回到之前的图像并产生问题。
我需要创建一个新grub.cfg文件，但我需要清除除 之外的所有不需要的 Linux 映像4.4.0-185。当我运行sudo apt --purge autoremove命令时，它会引发以下错误。

我一头雾水。当我使用时boot-repair，它给了我一个日志文件，你可以在这里找到它。

请帮助我，因为我不想浪费我的数据并让系统恢复正常。
