我正在全新安装 16.10，并尝试在其上安装 Docker。我添加了 PPA，更新了 apt，然后启动了：
sudo apt install docker-engine
它运行完美。
现在，当我重新启动时，我的 Wifi 无法被检测到！看来 docker 接口与我现有的网络接口产生了冲突。它甚至将其从 ifconfig 中删除。
编辑：这是之前/之后的一些命令输出：
$ cat /etc/network/interfaces
# interfaces(5) file used by ifup(8) and ifdown(8)
auto lo
iface lo inet loopback
（前后相同）
$ ifconfig -a

以下命令也未执行任何操作：
sudo systemctl restart network-manager
我正在使用一台没有以太网连接、只有 Wifi 的笔记本电脑。
sources.list中添加的PPA是：
deb https://apt.dockerproject.org/repo ubuntu-xenial main
答案1
研究表明，这可能与这个错误。如果是这样，解决方法是修改/etc/NetworkManager/NetworkManager.conf为
[main]
plugins=ifupdown,keyfile
[ifupdown]
managed=false
[keyfile]
unmanaged-devices=interface-name:docker0
这将使得 NetworkManager 忽略 docker 适配器。
