Ubuntu18.04网卡失效ifconfig interrupt 16 memory

Issue

因编译swap耗尽强制重启，发现系统无法上网。
ifconfig只有本地回路lo
ifconfig -a能看见eno1网卡，提示interrupt 16 memory xxxx

Solve

手动修复配置文件

sudo -i
service network-manager stop
rm /var/lib/NetworkManager/NetworkManager.state
touch /etc/NetworkManager/conf.d/10-globally-managed-devices.conf
vi /etc/NetworkManager/NetworkManager.conf
# set [ifupdown]managed=true
service network-manager restart

Reference

network manager says "device not managed" - Ask Ubuntu
