This seems to be a kernel regression that happened either in 4.4 or 4.2. I'll get more information on recreate soon. to get this off my system, here are my very sloppy notes http://paste.ubuntu.com/23117619/
essentially, you boot a cloud image with overlayroot enabled then 'apt-key add - <some-file'. Also can be recreated with a tempfile rename for some files. Ie, the way that atomic writes are often done, by writing to afile in the same dir and then renaming. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1618572 Title: cloud-init failing to configure sources and additional repository To manage notifications about this bug go to: https://bugs.launchpad.net/cloud-init/+bug/1618572/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
