There was an error during the CUPS operation: 'client-error-not-possible'.

當參考ubuntu18.04連接windows共享打印機 時有時可能會出現

“There was an error during the CUPS operation: 'client-error-not-possible'.”錯誤

通過查看 /var/log/cups/error_log日志並查看samba packages 就會發現缺少“samba-client”

解決方法：

sudo apt  install samba-client
systemctl restart cups.service

發現處理linux計算機的問題要善於看log 日志。
