解决Ubuntu 18.04报错：Called "net usershare info" but it failed: Failed to execute child process “net”

1. 问题描述

Ubuntu 18.04用着用着突然遇到如下错误：

Called "net usershare info" but it failed: Failed to execute child process “net” (No such file or directory)

错误来源是Ubuntu nautilus，触发时机是关闭nautilus时，如下图所示：

2. 解决方法

S1. 终端中运行如下命令安装samba-common-bin：

sudo apt install samba-common-bin

若执行完S1，关闭nautilus时出现如下错误，则继续执行S2。
