----==_mimepart_539ee1efef17d_383c3fdedf27b2a01208a8 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 7bit In Ubuntu, LTS point releases ship with hardware enablement kernels and X.org stacks backported from the latest corresponding non-LTS release by default, so that users can continue to install and use the LTS release on newer hardware. These enablement packages have a shorter support lifetime than the LTS release itself. The supported mechanism to continue with newer hardware on LTS releases for the full LTS support lifetime period is to upgrade to a newer hardware enablement package. This process must be manual, however, since we do not want to risk regressing installations. We have concluded that bumping the kernel and X.org versions is a major enough change that it is not suitable for an automatic update. Thus we must notify users of this need to update in any way we can, so that they can take action. We thought that the existing check_apt test is one appropriate place to alert users that an update is available. The underlying logic for the change to this plugin is: 0. Follow the existing behaviour to determine the number of updates and critical updates available. 1. If /usr/bin/hwe-support-status does not exist, do nothing different. This covers the case where users have not yet received the update that makes it available, or are using a distribution that does not provide HWE packs (eg. Debian currently). 2. Given that /usr/bin/hwe-support-status does exist, run it with --quiet. If an update is required, it will exit with a non-zero status. 3. If an update is required, bump the number of "critical updates" detected. 4. Report this as normal. 5. I expect a user who wants more information to run "check_apt -v". In this case, /usr/bin/hwe-support-status is run with --verbose and its output is printed. This prints a human-readable EOL notification message with more information. On Ubuntu, this links to a wiki page which we can update with any frequently asked questions. Though the need for this patch comes from Ubuntu, I've written it in a way that Debian could use the same mechanism in future. There are no Ubuntu-specific parts in this patch itself.
