当我启动我的 Ubuntu 服务器时，DNS 解析不起作用。您可以通过查看 resolv.conf 最容易地看到这一点：
~ # cat /etc/resolv.conf
# Dynamic resolv.conf(5) file for glibc resolver(3) generated by resolvconf(8)
# DO NOT EDIT THIS FILE BY HAND -- YOUR CHANGES WILL BE OVERWRITTEN
# 127.0.0.53 is the systemd-resolved stub resolver.
# run "systemd-resolve --status" to see details about the actual nameservers.
然后我启用已解决的服务：
~ # systemctl enable systemd-resolved.service
事情按预期工作：
~ # cat /etc/resolv.conf
# Dynamic resolv.conf(5) file for glibc resolver(3) generated by resolvconf(8)
# DO NOT EDIT THIS FILE BY …我现在无法安装或删除任何软件包。每个 aptitude 或 dpkg 命令都会失败
dpkg: error: duplicate file trigger interest for filename
`/usr/share/icons/hicolor' and package `hicolor-icon-theme'
我尝试了dpkg 中的 sed 技巧：错误：重复文件触发了文件名 `/usr/lib/gio/modules' 和包 `libglib2.0-0:i386' 的兴趣，但这对我不起作用。
我正在使用 3.2.0-32 运行 12.10。
