I think the issue is quite simple actually. Bionic uses net plan, everything before that uses e/n/i. In trusty, curtin wrote the network configuration. In latest versions, Curtin now doesn’t do the network configuration, and actually tells cloud-unit to do it by passing the configuration.
So what I think is happening is that curtin writes e/n/i and cloud-unit actually never writes net plan. So I would say that bionic deployment is not supported on 1.9 due to curtin. ** Changed in: maas Status: New => Incomplete ** Also affects: curtin (Ubuntu) Importance: Undecided Status: New ** Also affects: curtin (Ubuntu Trusty) Importance: Undecided Status: New ** Changed in: curtin (Ubuntu) Status: New => Incomplete ** Changed in: curtin (Ubuntu) Status: Incomplete => Invalid -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1791006 Title: deploying Ubuntu 18.04 with MAAS 1.9.5 fails during the final boot To manage notifications about this bug go to: https://bugs.launchpad.net/maas/+bug/1791006/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
