（请参阅下面的更新 1、2 和 3）
今天我更新了主机系统，然后重新启动后 LXD 守护进程没有启动。
它给出了错误
failed to create listening socket for 10.104.52.1: Address already in use
我能做些什么？
我有：
- Ubuntu 16.04.3 LTS
- lxd 2.16 3346 规范-（Snap 版本）
我用来启动的命令
sudo systemctl start snap.lxd.daemon.service
从系统日志中提取：

从这里开始它进入无限循环并且永远不会开始
==================== 更新 3 ====================================
我有一台出现无限重启循环错误的物理机和一台可以正确重启的虚拟机。
在物理机器中（在循环过程中出现错误）：
sysop@s4:~$ sudo brctl show
bridge name bridge id STP enabled interfaces
lxdbr0 8000.fe049a888031 no veth7KVBSH
vethFPOTVD

vethYWVLD4
lxdbr1 8000.fe503c909805 no vethGDM55D
virbr1 8000.525400d8609d yes virbr1-nic
在虚拟机中（正确重启）：
sysop@vx00:~$ sudo brctl show
[sudo] password di sysop:
bridge name bridge id STP enabled interfaces
lxdbr0 8000.fe4f7f04c603 no veth13QLME

vethX7TJ8L
lxdbr1 8000.fec3f10606ce no vethOXYX5G
virbr1 8000.fe5400ffa6aa yes vnet1
这有关系吗？
答案1
读取消息“无法为 10.104.52.1 创建监听套接字：地址已被使用”
因此选择另一个 IP 地址，例如 10.104.52.2 或类似的
答案2
回复我自己 解决了
我在同一台机器上安装了 bind9，它在 dnsmasq 上优先
处于无限循环状态：
