我在运行中遇到问题avahi-daemon 0.6.31。
我也卸载并重新安装，但启动时总是出现错误：

跑步
systemctl status avahi-daemon.service
它总是返回：

而 avahi 用户和组都在 /etc/shadow 和 /etc/group 中。通过互联网查找错误消息：
Failed to find user 'avahi'
没有返回非常有用的结果。
什么可能导致了这个问题？

https://archlinuxarm.org/forum/viewtopic.php?f=31&t=6408 这为我解决了该问题。
Go edit /etc/avahi/avahi-daemon.conf
Find the line:
"#disallow-other-stacks=no"
and change to
"disallow-other-stacks=yes"
这个标志显然是现在导致 avahi 尝试使用 SO_REUSEPORT 的原因（而将其变为是则会禁用这种新行为。）文档表明这是一种机制，可以同时适应具有多个 mdns 处理程序的恶意设置。
