wide-dhcpv6は、存在しないインターフェースを使用しているため、起動に失敗します

私とwide-dhcpv6を再起動しようとすると、journalctlでこれを取得します

私の設定ファイルにあったインターフェースを使用しようとしましたが、名前を変更して設定の名前を置き換えました

ciaran@router:/etc/wide-dhcpv6$ cat dhcp6c.conf
##
## This is/etc/wide-dhcpv6/dhcp6c.conf
##
## Replace the existing configuration with this one.

# Send a PD request on the external facing interface
# send ia-pd says ask for a prefix
# the script is run when the prefix is acquired
interface wan0 {
 send ia-pd 2;
 script "/etc/wide-dhcpv6/dhcp6c-script";
};

# Upon receiving a prefix use the
# information to set the internal facing interface
id-assoc pd 2 {
 prefix-interface wlan0 {
  ifid 1;
  sla-id 1;
  sla-len 0;
 };
};

## End of config.

それが間違ったインターフェースを使用しようとする理由は何ですか？

/ etc/defaultにプレフィックスを要求するアドレスを設定するファイルがありました

ciaran@router:/etc/default$ cat wide-dhcpv6-client
# Defaults for dhcpv6 client initscript
# Used by /etc/init.d/wide-dhcpv6-client

# Interfaces on which the client should send DHCPv6 requests and listen to
# answers. If empty, the client is deactivated.
INTERFACES="enp0s31f6"

# Verbose level for syslog. Default is 0 (0: minimal; 1: info; 2: debug)
#VERBOSE=0

それをwan0に変更した後、うまくいきました
