I had the same problem after moving my ubuntu vm to a different host. The following steps worked for me, the reloading of the kernel modules might not be required, cannot reproduce as it is working now. I guess the network-manager is broken.

  • unload /reload the kernel modules
  • list the network adapters to get the name of the device (in my case it was „ens33“)
  • get an ip for the device
  • do an apt-get update / upgrade
  • reinstall network-manager
sudo rmmod e1000
sudo rmmod e1000e
sudo rmmod igb

sudo modprobe e1000
sudo modprobe e1000e
sudo modprobe igb

sudo dhclient ens33

sudo apt-get update && sudo apt-get upgrade
sudo apt-get purge network-manager
sudo apt-get install network-manager
