This is not a good user experience, specially because the user can make an uninformed decision of keeping the old config file, which will make unattended-upgrades to not work as we expect. [Test case] To reproduce the issue, you can: 1. Launch a trusty vm 2. Perform a do-release-upgrade and observe that you will be prompted with the 50unattended-upgrades change To verify that the error is fixed: 1. Launch a trusty vm 2. Import this ppa into the system: https://launchpad.net/~lamoura/+archive/ubuntu/unattended-upgrades-ppa 3. Configure do-release-upgrade to allow using third parties during upgrade 4. Run a do-release-upgrade 5. Verify the prompt is no longer there and that we end up with the expected 50unattended-upgrades config file [Where problems could occur] The changes in this package should only surface during an upgrade operation. With this change, we are now delivering a new file to the system and configuring postinst to use it. Because of that, we believe this is the only scenario that could be affected in case of a regression is discovered in the package. [Discussion] When upgrading from trusty to xenial, we are prompted about config changes on 50unattended-upgrades with the following diff: --- /etc/apt/apt.conf.d/50unattended-upgrades root.root 0644 2017-05-08 19:21:39 +++ /etc/apt/apt.conf.d/50unattended-upgrades.ucftmp root.root 0644 2020-02-17 18:03:38 @@ -1,11 +1,13 @@ // Automatically upgrade packages from these (origin:archive) pairs Unattended-Upgrade::Allowed-Origins { + "${distro_id}:${distro_codename}"; "${distro_id}:${distro_codename}-security"; // Extended Security Maintenance; doesn't necessarily exist for // every release and this system may not have it installed, but if // available, the policy for updates is such that unattended-upgrades // should also install from here by default. - "${distro_id}ESM:${distro_codename}"; + "${distro_id}ESMApps:${distro_codename}-apps-security"; + "${distro_id}ESM:${distro_codename}-infra-security"; // "${distro_id}:${distro_codename}-updates"; // "${distro_id}:${distro_codename}-proposed"; // "${distro_id}:${distro_codename}-backports"; The reason we are presented with this diff is that the xenial package does not contain a md5sum history file that informs ucf about all the supported configs for 50unattended-upgrades. To fix that upgrade problem, we are prosing the following changes on the xenial package of unattended-upgrades: - Add 50unattended-upgrades.md5sum file into the xenial package - Add md5sum of the current xenial 50unattende-upgrades file into the md5sum history file - Modify ucf command in postinst to be aware of the md5sum history file See the changelog entry below for a full list of changes and bugs. We have performed a manual test with a modified version of the xenial package: https://launchpad.net/~lamoura/+archive/ubuntu/unattended-upgrades-ppa Using that package, we were able to verify that the config change prompt no longer happens from trusty to xenial. Since we are modifying are features on unattended-upgrades, just adding a new file to package, we don't believe there is any regression potential == Changelog == * data: add md5sum history file on the data folder - This file contains md5sum of several supported 50unattended-upgrades config files * data: add xenial md5sum of 50unattented-upgrades into md5sum file * debian/postint: make ucf command reference the md5sum history file To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/unattended-upgrades/+bug/1915547/+subscriptions -- Mailing list: https://launchpad.net/~touch-packages Post to : touch-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~touch-packages More help : https://help.launchpad.net/ListHelp
