Hello Scott, or anyone else affected, Accepted nplan into artful-proposed. The package will build now and be available at https://launchpad.net/ubuntu/+source/nplan/0.32~17.10.4 in a few hours, and then in the -proposed repository.
Please help us by testing this new package. See https://wiki.ubuntu.com/Testing/EnableProposed for documentation on how to enable and use -proposed.Your feedback will aid us getting this update out to other Ubuntu users. If this package fixes the bug for you, please add a comment to this bug, mentioning the version of the package you tested and change the tag from verification-needed-artful to verification-done-artful. If it does not fix the bug for you, please add a comment stating that, and change the tag to verification-failed-artful. In either case, without details of your testing we will not be able to proceed. Further information regarding the verification process can be found at https://wiki.ubuntu.com/QATeam/PerformingSRUVerification . Thank you in advance! ** Changed in: nplan (Ubuntu Artful) Status: New => Fix Committed ** Tags added: verification-needed verification-needed-artful -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to systemd in Ubuntu. https://bugs.launchpad.net/bugs/1732002 Title: cloud images in lxc get ipv6 address Status in nplan package in Ubuntu: Fix Released Status in systemd package in Ubuntu: New Status in nplan source package in Artful: Fix Committed Bug description: [Impact] All users of netplan. [Test case] == LXD containers == 1) Start an LXD container (artful or bionic) 2) Verify that an IPv6 address is present 3) Verify that the system is brought up in a reasonable time (does not wait 2 minutes to be reachable). == servers / cloud instances == 1) Start a bionic system, with no IPv6 connectivity (no router to advertise a prefix) 2) Verify that the system boots quickly (does not wait 2 minutes to be reachable). [Regression potential] Since this changes default IPv6 behavior, care should be taken to validate that systems are maintaining IPv6 connectivity when it is available, and similarly that systems where no IPv6 connectivity is available on the network are behaving correctly: there should not be long boot delays, and no extra IPv6 addresses aside from link-local addresses generated by the kernel. -- I noticed that lxd (lxc list) reports that an lxc container has an ipv6 address in artful or bionic. It does not list this in xenial or zesty. I suspect this change occurred in the switch over to netplan/networkd. This may at first seem harmless or even desired, but note that the user configuration did not request ipv6 config, so its presence is a bug. $ for rel in xenial zesty artful bionic; do lxc launch ubuntu-daily:$rel $rel-demo; done Creating xenial-demo Starting xenial-demo ..
