我有一本包含以下任务的 ansible 剧本
- name: Get aptitude for upgrade
apt: pkg=aptitude state=present
- name: Update APT package cache
apt: update_cache=yes cache_valid_time=3600
当我添加
- name: Upgrade APT to the latest packages
apt: upgrade=safe
eth0 接口神奇地消失了。
猫/等/网络/接口：
auto lo
iface lo inet loopback
auto etho0
iface eth0 inet dhcp
是否配置apt: upgrade=safe 之前：
eth0 Link encap:Ethernet HWaddr b8:27:eb:9e:16:fd

我正在运行全新的 Ubuntu 服务器 16.04 LTS。知道为什么 eth0 会消失吗？显然 apt: upgrade=safe 是问题所在，但为什么呢？
配置文件令人惊讶的是给出了不同的输出，但是 eth0 仍然缺失：
答案1
安装网络管理器后问题消失
- name: Get network-manager
apt: state=installed pkg=network-manager
