通过 systemd 激活单元“dbus-org.freedesktop.resolve1.service”失败：未找到单元 dbus-org.freedesktop.resolve1.service

Question

我正在使用 manjaro/arch linux，我在系统日志中看到以下错误消息。

journalctl -f 
...
dbus-daemon[798]: [system] Activating via systemd: service name='org.freedesktop.resolve1' unit='dbus-org.freedesktop.resolve1.service' requested by ':1.4' (uid=0 pid=799 comm="/usr/bin/>
dbus-daemon[798]: [system] Activation via systemd failed for unit 'dbus-org.freedesktop.resolve1.service': Unit dbus-org.freedesktop.resolve1.service not found.
...

我该如何解决这个问题

Answer 1

此问题与network-manager和相关systemd-resolved.service。

在阅读了manjaro 论坛和arch wiki 之后

你有2个选择

配置网络管理器不使用 systemd-resolved.service

vim /etc/NetworkManager/conf.d/no-systemd-resolved.conf

有了这个内容：

[main]
systemd-resolved=false

激活并使用 systemd-resolved.service

检查它是否正在运行和启用

systemctl status systemd-resolved.service
? systemd-resolved.service - Network Name Resolution
  Loaded: loaded (/usr/lib/systemd/system/systemd-resolved.service; disabled; vendor preset: enabled)
  Active: inactive (dead)

          https://www.freedesktop.org/wiki/Software/systemd/writing-resolver-clients

启用并启动它。

systemctl enable systemd-resolved.service

这解决了日志中出现的错误。
