[Bug 1619258] Re: netplan should allow NICs to be disconnected and not stall the boot
What is the actual fix for this. I have run into this multiple times. Is there a specific edit that needs to be made to the stanza in netplan? After reviewing the netplan docs I was unable to find a corresponding directive for allow-hotplug with /etc/network/interfaces. $ lsb_release -a No LSB modules are available.

Yeah, we're kinda talking about two things, the problem with ubuntu core and the problem with the artful daily-live server installer.

Re: [Bug 1619258] Re: netplan should allow NICs to be disconnected and not stall the boot
Yes, I think it probably is. I want to change the server live-install image to dhcp on wired interfaces by default which will mostly work around the problem but a real fix/understanding is clearly also required.

[Bug 1619258] Re: netplan should allow NICs to be disconnected and not stall the boot
setting this back to confirmed this is definitely still an issue (and always has been), very easily to reproduce on a raspberry pi3 with Ubuntu Core that you only configure for wifi... if you go with the defaults in the network config of subiquity the eth0 device stays enabled and defaults to dhcp but nothing in systemd will take into account if a physical wire is connected on boot so it will blindly wait for the interface to be up until the timeout hits. adding something like "allow-hotplug" to nplan would solve this. alternatively simply having systemd-networkd check for physical status and skipping the unwired device would help too. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1619258 Title: netplan should allow NICs to be disconnected and not stall the boot To manage notifications about this bug go to: https://bugs.launchpad.net/snappy/+bug/1619258/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

[Bug 1619258] Re: netplan should allow NICs to be disconnected and not stall the boot
Which services in snappy actually stall/wait on network-online.target? On my yakkety desktop system these are just rc-local.service, kerneloops.service, and lxd.service -- neither of which are really required to log into the device or start services (even ssh.service doesn't block on network-online.target). So not implementing network-online.target would be a workaround, but I believe eventually this would not help -- as services which *legitimately* need to wait until the network is up (such as network mounts, backup software, etc.) would then unnecessarily fail. I believe it is a more robust design to always let network- online.target do its job but avoid depending on it in services which don't really require network. Can you please copy the output of "systemctl list-jobs" when this happens? This should show the bits that wait on network-online.target. > netplan should make the system check the physical link status when trying to bring up a network device instead of stalling the boot. Both networkd and NM already do this -- they bring up an interface once it appears and gets a carrier. However, s-n-wait-online waits until all configured links appear (with a timeout of 2 minutes), which is usually what you want with services that depend on network-online. So I believe completely disabling wait-online is not the right way. We might want to add syntax and functionality to mark devices like "allow- hotplug" in ifupdown, though. ** Changed in: nplan (Ubuntu) Status: Confirmed => Incomplete -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1619258 Title: netplan should allow NICs to be disconnected and not stall the boot To manage notifications about this bug go to: https://bugs.launchpad.net/snappy/+bug/1619258/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
