Question

我想在网络打印机上清理所有打印作业

cupsenable [printername]
cancel -a [printername]
cancel: purge-jobs failed: Forbidden

用户是＆＃34; lp＆＃34;的成员组

我还在@etc/cups/cupsd.conf文件的限制中添加了@OWNER，其中清除作业和取消作业是

之后我关闭了我的会话并再次尝试，再次出现同样的错误。

之后我明确添加了我想取消作业的用户

关闭我打开的会话并再次尝试 - ＆gt;没有

也许我错过了什么？

这是我的cupsd.conf：

也许我错过了一些预约？

我无法让用户成为超级用户，因为客户正在使用此帐户，他不应该是服务器上的超级用户。

Answer 1

我通过谷歌搜索到达了这里

取消：取消工作失败：禁止

我的解决方法是授予lp组运行cups命令的权限，然后将用户添加到lp组中。

首先，将lp添加到/etc/cups-files.conf中的系统组中...

# Administrator user group, used to match @SYSTEM in cupsd.conf policy rules...
SystemGroup sys root lp

重新启动杯子...

systemctl restart cups

将用户添加到lp组。

usermod -a -G lp user1

user1现在可以运行

cancel PRINTER-12345

并使用杯子网站上的[取消作业]按钮（将提示您登录）。

From the cupsd.conf man page

要求用户{user-name | @ group-name} ...

指定经过身份验证的用户必须与指定用户之一匹配   或成为其中一个命名组的成员。组名“ @SYSTEM”   对应于SystemGroup指令定义的组列表   在cups-files.conf（5）文件中。

tldr;

/etc/cupsd.conf授予@SYSTEM权限。

/etc/cups-files.conf SystemGroup定义了@SYSTEM。

Answer 2

通过将具有cancel命令的用户添加到sudoers文件

来解决

sonex    ALL=(ALL)     NOPASSWD: /etc/bin/cancel -a *

似乎在某种程度上没有办法通过配置文件解决它只清除单个打印作业

Cups cancle工作给出了禁止的错误
