This has nothing to do with network, as mentioned earlier netplan is masked and ifupdown works as expected. Moreover it is known EXACTLY what happens (in initramfs):
local_top/aoe calls configure_networking In absence of any kernel args, configure_networking tries to bring up every interface, by launching dhcpc for 3(?) seconds. This succeeds for interface that will be configured as part of bridge by ifupdown later, so bridge is left unconfigured and network is lost. The current workaround is to add ip=none to kernel line The proper fix is to change configure_networking to have a mode/arg where it brings up network interfaces bot does not try to assign ip addresses, and call it this way from local_top/aoe . Probably even split configure_networking into two functions... p.s. I can predict the future though (I have such a gift) - the resolution would be "AOE is used by 0.000000000000000001% of ubuntu users, we power the word and store petabytes of data, mark this as enhancement for a future version N+5". -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1905472 Title: Something starts dhcclient for every intrface on boot To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/ifupdown/+bug/1905472/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
