Posted by Dongbo on November 1, 2019

有几次Vmware进程卡死直接关掉之后，再开机Ubuntu就没法联网了，setting中网络连接的设置也找不到了。

sudo service network-manager stop  
sudo rm /var/lib/NetworkManager/NetworkManager.state  

vim /etc/NetworkManager/NetworkManager.conf 

  # 这是文档内容
  
  # [main]
  # plugins=ifupdown,keyfile
  #
  # [ifupdown]
  # managed=false
  #
  # [device]
  # wifi.scan-rand-mac-address=no

# 把 managed=false  改成 managed=true    

sudo service network-manager start

[ifupdown]
managed
If set to true, then interfaces listed in /etc/network/interfaces are managed by NetworkManager. If set to false, then any interface listed in /etc/network/interfaces will be ignored by NetworkManager. Remember that NetworkManager controls the default route, so because the interface is ignored, NetworkManager may assign the default route to some other interface.

但是查了文档，也没搞懂改成true的必要性，原post也没有任何解释。感觉只需要启动network-manager就可以了，下次有机会尝试。
