新裝了linux 18.04後， 掛載其他盤時，遇到了如下錯誤
$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.
後發現缺少 cifs-utils 包， 導致有此錯誤
安裝 cifs-utils 包
$sudo apt-get install cifs-utils

Refer to the mount.cifs(8) manual page (e.g. man mount.cifs)
恩， 似乎剛剛那個錯誤解決了， 再來解決此錯誤。
網上說需要增加選項： vers=1.0
參考 https://blog.csdn.net/NICK1211/article/details/80495497
恩，成功了。
$sudo mount -t cifs -o username=xxxx,vers=1.0 //172.16.2.225/SW_Test/ /media/SW_TEST
[sudo] password for xxxx:
