dhclient“无法绑定到 dhcp 地址”错误

dhclient“无法绑定到 dhcp 地址”错误

启动网络管理器时,我不断从 dhclient 收到以下错误消息:

无法绑定到 dhcp 地址:无法分配请求的地址。请确保没有其他 dhcp 服务器正在运行,并且 /etc/inetd.conf 中没有 dhcp 或 bootp 条目。另外,请确保您没有运行包含 bootp 服务器的 HP JetAdmin 软件。

此版本的 ISC DHCP 基于 ftp.isc.org 上提供的版本。已添加功能并对基本软件版本进行其他更改,以使其更好地与此发行版配合使用。

请通过 Red Hat Bugzilla 网站报告此软件: http://bugzilla.redhat.com

据我所知,我没有运行 dhcp 服务器,/etc 中也没有文件 inetd.conf,也没有运行 HP JetAdmin。我尝试搜索互联网,但找不到解决方案。我也不完全理解这个错误消息。有人能帮我吗?

根据要求,这些是来自各种命令的输出:

我认为这与 IPv6 有关,因为目前我的 ISP 不支持 IPv6。
