** Description changed: Ubuntu 20.04 server amd64, running as virtual machine on FreeNAS-11.3-U3.2. Network interface was configured with driver VirtIO, and network interface is bridged at FreeNAS. The issue is that I have DHCP server in my LAN and Ubuntu installer gets IPv4 address and applies updates from internet. Install process is OK. - Once installation is finished, reboot is required but Ubuntu will not - start, EFI issue has to be fixed first; Ubuntu on FreeNAS has problem - with EFI, it has to be manually fixed; it is known issue, solution is - here: https://www.ixsystems.com/community/threads/howto-how-to-boot- - linux-vms-using-uefi.54039/ - - Once EFI is fixed and Ubuntu boots, no IP address is assigned to enp0s4 - interface, so Ubuntu 20.04 server has no network connectivity. I can - manually force IP address allocation with command "sudo dhclient enp0s4" - and it works but that is just a workaround. IP address should be - allocated automatically during server boot... + Once installation is finished, reboot is required but Ubuntu will start + but no IP address is assigned to enp0s4 interface, so Ubuntu 20.04 + server has no network connectivity.

I have older Ubuntu machines on the same FreeNAS box and those work fine, so I assume there is a bug in Ubuntu 20.04 and DHCP client is broken or not reliable... :-( Some problem in netplan utility?? + + I tried to install fresh 18.04.4 to my FreeNAS box and I see the same + problem, no IP address is assigned during boot.
