![Cups Delay、DBus 和 Colord](https://linux22.com/image/899700/Cups%20Delay%E3%80%81DBus%20%E5%92%8C%20Colord.png)
我遇到了 CUP 问题;打印延迟了 20-30 秒。我将其归结为 dbus 问题,这是由于在启动 cups 时 colord 无法正常启动而导致的。如果我手动启动 colord,打印可以正常进行,不会出现延迟。但它总是失败,并显示一条看似不正确的消息
# systemctl status colord.service
● colord.service - Manage, Install and Generate Color Profiles
Loaded: loaded (/lib/systemd/system/colord.service; static; vendor preset: enabled)
Active: failed (Result: resources)
Apr 11 06:08:37 sysA systemd[1]: colord.service: Failed to run 'start' task: No such file or directory
Apr 11 06:08:37 sysA systemd[1]: Failed to start Manage, Install and Generate Color Profiles.
Apr 11 06:08:37 sysA systemd[1]: colord.service: Unit entered failed state.
Apr 11 06:08:37 sysA systemd[1]: colord.service: Failed with result 'resources'.
错误消息不太好;启动任务存在,因此它肯定在寻找其他文件。我该如何调试它?
