dhclient Erro “Não é possível ligar ao endereço DHCP”

0

Continuo recebendo a seguinte mensagem de erro do dhclient ao iniciar o Network Manager:

Can't bind to dhcp address: Cannot assign requested address. Please make sure there is no other dhcp server running and that there's no entry for dhcp or bootp in /etc/inetd.conf. Also make sure you are not running HP JetAdmin software, which includes a bootp server.

This version of ISC DHCP is based on the release available on ftp.isc.org. Features have been added and other changes have been made to the base software release in order to make it work better with this distribution.

Please report for this software via the Red Hat Bugzilla site: http://bugzilla.redhat.com

Tanto quanto eu sei, eu não tenho um servidor dhcp em execução, nem existe um arquivo inetd.conf em / etc, também não estou executando o HP JetAdmin. Eu tentei pesquisar na internet, mas não consigo encontrar uma solução. Nem entendo totalmente essa mensagem de erro. Alguém pode me ajudar?

Como solicitado. estes são os resultados dos vários comandos:

Acho que tem algo a ver com o IPv6, que atualmente não é suportado pelo meu ISP.
