[Linux相关] mount(2) system call failed: Operation not supported 解决方案

新装了linux 18.04后， 挂载其他盘时，遇到了如下错误

$sudo mount -t cifs -o username=xxx //172.16.x.xxx/SW_Test/ /media/SW_TEST
mount: /media/SW_TEST: mount(2) system call failed: Operation not supported.

后发现缺少 cifs-utils 包， 导致有此错误

安装 cifs-utils 包

$sudo apt-get install cifs-utils
