Public bug reported: 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... 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?? ** Affects: netplan.io (Ubuntu) Importance: Undecided Status: New -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1881832 Title: Ubuntu server 20.04 fails to get IP address from DHCP server (no network connectivity) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/netplan.io/+bug/1881832/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
