Engineering Team, which is subscribed to cloud-init. https://bugs.launchpad.net/bugs/1628337 Title: cloud-init tries to install NTP before even configuring the archives Status in cloud-init: Fix Committed Status in cloud-init package in Ubuntu: Fix Released Status in cloud-init source package in Xenial: Fix Released Bug description: == Begin SRU Template == [Impact] When told to configure ntp, and the ntp package is not installed in an image, cloud-init will attempt to install the package. The problem here is that it currently tries to install the package before it configures apt. As a result, no apt proxy or mirror configuration is setup, and the stock image apt config is used. [Test Case] ## Failure can be shown like this: $ cat > user-data <<END #cloud-config ntp: servers: ['ntp.ubuntu.com'] apt: primary: - arches: [default] uri: http://us.archive.ubuntu.com/ubuntu/ END $ release=xenial $ name=x1 $ lxc init ubuntu-daily:$release $name "--config=user.user-data=$(cat user-data)" # simulate a mirror that can't be reached by changing # /etc/apt/sources.list to have a bogus mirror. # what should happen is that cloud-init should apply apt config changes # and render /etc/apt/sources.list from /etc/cloud/templates/ # and do the mirror substitution first. # # The bug is that cloud-init does not render apply the apt # config before ntp runs and requests the package installation. $ lxc file push - $name/etc/apt/sources.list <<EOF deb http://bogus.example.com/ubuntu/ $release main restricted universe EOF $ lxc start $name # wait for it to boot $ while ! lxc exec $name -- [ -e /run/cloud-init/result.json ]; do sleep 1; done $ lxc file pull $name/var/log/cloud-init-output.log - | egrep "^[EW]:" W: Failed to fetch http://bogus.example.com/ubuntu/dists/xenial/InRelease Could not resolve 'bogus.example.com' W: Some index files failed to download. They have been ignored, or old ones used instead. E: Unable to locate package ntp EOF ## The fix can be shown applied by subsequently # push the broken sources.list back into image. $ lxc file push - $name/etc/apt/sources.list <<EOF deb http://bogus.example.com/ubuntu/ $release main restricted universe EOF ## Now update container, clean and reboot to show first boot $ lxc exec $name -- sh -c ' p=/etc/apt/sources.list.d/proposed.list echo deb http://archive.ubuntu.com/ubuntu xenial-proposed main > "$p" && apt-get update -q && apt-get -qy install cloud-init' $ lxc exec $name -- sh -c ' cd /var/lib/cloud && for d in *; do [ "$d" = "seed" ] || rm -Rf "$d"; done rm -Rf /var/log/cloud-init*' $ lxc file pull $name/var/log/cloud-init-output.log - | egrep "^[EW]:" || echo "FIX WORKED." [Regression Potential] The 'ntp' function is fairly new, and is only used if a user specifies an ntp configuration as shown above. Regression chance is low then and should be restricted to scenarios where users are providing the ntp configuration. == End SRU Template == cloud-init tries to install NTP package before it actually configures /etc/apt/sources.list. In a closed MAAS environment where MAAS is limited to access to us.archive.ubuntu.com , cloud-init is trying to access to archive.ubuntu.com. In commissioning, however, cloud-init is doing this: 1. cloud-init gets metadata from MAAS 2. cloud-init tries to install NTP from archive.ubuntu.com 3. cloud-init configures /etc/apt/sources.list with us.archive.ubuntu.com 4. cloud-init installs other packages.
