I think this is still an issue. At least, I made a new Xenial box from ami-c1167eb8 (Amazon AWS, eu-west-1, xenial, 16.04, amd64, hvm-ssd, 20180205). Is that a 'daily'?

So the reason that this regressed in xenial is that we've changed the way in which we build images, and the workaround for this was only being applied to PV images. I'm now building test images with the workaround applied to HVM and PV images, to confirm that my reasoning is sound. ** Changed in: cloud-images Status: Confirmed => In Progress -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1485685 Title: Users are prompted on upgrade of cloud images To manage notifications about this bug go to: https://bugs.launchpad.net/cloud-images/+bug/1485685/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

[Bug 1485685] Re: Users are prompted on upgrade of cloud images
Note bug 1323772 (marked as duplicate) with more commentary, description
of other workarounds and links to other bugs which may all be the same
issue.
** Description changed:
Steps to reproduce (use case):
1. Fire up a Trusty cloud image.
2. Run: sudo apt-get update sudo apt-get -y dist-upgrade
Steps to reproduce (developer):
1. Fire up an older image that does not contain the newest grub2 SRU.
Example:
http://cloud-images.ubuntu.com/trusty/20150706/trusty-server-cloudimg-amd64-disk1.img.
I'm using uvt-kvm create --backing-image-file
trusty-server-cloudimg-amd64-disk1.img testvm to do this.
2. Run: sudo apt-get update sudo apt-get -y dist-upgrade
Expected results: completes without prompts.
Actual results: prompts the user for input to resolve a manually
changed /boot/grub/menu.lst.
User impact: this messes up automation; it is a common use of cloud
images for users to automate their server deployments which generally
involves running a dist-upgrade and then bootstrapping some kind of
configuration management system.
This means that we cannot SRU grub2 without breaking some set of users
in a fairly common use case of cloud images until users start using
newer images with the new SRU'd grub2 rolled in.
- Workaround: users can use something like: UCF_FORCE_CONFOLD=1 apt-get
- update apt-get -y dist-upgrade. Note that to avoid prompts in various
- other cases users should also set DEBIAN_FRONTEND=noninteractive, run
- apt-get with -o Dpkg::Options::=--force-confdef -o Dpkg::Options
- ::=--force-confold and consider redirecting stdin from /dev/null.
+ Workaround: users can use something like: apt-get update

Investigation:
I noticed that running sudo update-grub-legacy-ec2 before dist-upgrade
works around the problem. This is because ucf updates the entry for
/run/grub/menu.lst in /var/lib/ucf/hashfile, at which point it doesn't
believe that the configurable snippet in menu.lst has changed locally in
a future run.
I suspect that menu.lst is being changed without ucf being updated in
the image build process. Line 421 _xchroot ${rootd} /usr/bin/ucfr
--purge grub /var/run/grub/menu.lst in vmbuilder-cloudimg-fixes (r699)
looks like it works around the issue, but I don't think the workaround
is working because calling /usr/bin/ucfr --purge grub
/var/run/grub/menu.lst doesn't clear the entry from
/var/lib/ucf/registry after the instance is launched either. It seems
that ucfr is normalising the path to /run/grub/menu.lst but the registry
stores the denormalised path so it fails to match.

[Bug 1485685] Re: Users are prompted on upgrade of cloud images
At the root of this issue is ucf. The ucfr command will store a path that contains symlinks during insertion but will only match the symlink- resolved path when attempting removal. Cloud image builds modify grub's menu.lst but have attempted to purge the ufc registry entry. This bug in ucf causes the registry removal to fail. This was partially fixed upstream in 3.0028[1] so that future additions to the registry would be symlink-resolved as well; however it does not address upgrade such that the user still can not remove an entry containing a symlink. For our current cloud image users, we can ensure the entry is properly removed during image creation for new images, ideally with a fixed ucf package that benefits everyone, but for images in the field the user would need to remove the registry entry[2] and this is a manual edit of the registry file without further patches to upstream ucf.
