我尝试在 Ubuntu 16.04 上通过 WIFI 安装佳能 pixma 扫描仪。我已按照教程操作RUN=yes：/etc/默认/saned
并改变了 /etc/sane.d/saned.conf未选中 192.168.0.1/24。我甚至：sudo adduser saned lp
和：sudo adduser $USER saned
和：sudo -s
su -s /bin/bash saned
还我添加：sudo systemctl start saned.socket
和：sudo systemctl enable saned.socket
当我这样做时：sudo service saned restart
我得到
"Failed to restart saned.service: Unit saned.service is masked"
无法将我的扫描仪（Canon Pixma MG5750）连接到 ubuntu！提前感谢您的帮助
