`debsums -c` returns the error of /sbin/start-stop-daemon

[Shih-Yuan Lee]

[Impact]

 * Affects Canonical OEM images for Dell on focal and jammy

[Test Plan]

 * Built Canonical OEM images for Dell on focal or jammy that includes the latest Ubiquity packages from *-proposed or *-updates.

 * Use the customized image to install Ubuntu system

 * Install debsums after the installation to check the system.

[Where problems could occur]

 * N/A

[Other Info]

 * I have built and included the customized Ubiquity packages that included the patch for focal and jammy so there should also be no problem after we finished the SRU updates.

[Original Bug Description]

1) The release of Ubuntu you are using, via 'lsb_release -rd' or System -> About Ubuntu
Description: Ubuntu 22.04 LTS
Release: 22.04

2) The version of the package you are using, via 'apt-cache policy pkgname' or by checking in Software Center
ubiquity 22.04.16

3) What you expected to happen
`debsums -c` returns no error.

4) What happened instead
`debsums -c` returns the error of /sbin/start-stop-daemon

We made the OEM jammy base image for Dell that contains dpkg 1.21.1ubuntu2 and then use dell-recovery (Ubiquity plugin) fish mechanism to install/upgrade dpkg 1.21.1ubuntu2.1.

Because Ubiquity will rename it to /sbin/start-stop-daemon.REAL and provide a fake /sbin/start-stop-daemon during the installation.
When installing newer dpkg, /sbin/start-stop-daemon will be replaced. However Ubiquity will rename /sbin/start-stop-daemon.REAL back to /sbin/start-stop-daemon after the installation.
So /sbin/start-stop-daemon will be kept as the older one.
That is why the issue happens.

This bug was fixed in the package ubiquity - 22.10.4

---------------
ubiquity (22.10.4) kinetic; urgency=medium

  [ Shih-Yuan Lee (FourDollars) ]
  * Use dpkg-divert /sbin/start-stop-daemon unconditionally instead of just renaming it conditionally. (LP: #1978931)

  [ Sebastien Bacher ]
  * plugin-viewer-gtk.py: specify the gtk version to use and fix a warning
  * 22.10.3 upload included: Update the ubiquity icons for the brand
    refresh. Thanks to the Yaru team.

There will be no more point releases of focal, which means that this change is very low-risk with respect to focal. But in that case, is it necessary for this change to go in the archive, as opposed to in a Dell-specific archive, since there will also be no other ubiquity SRU changes in focal to worry about merging?

[Shih-Yuan Lee (fourdollars)]

Could we still merge the change into focal and release it into Ubuntu archives? Although there is no point release for focal, will we stop the daily build for focal?

[Steve Langasek (vorlon)]

Yes, we have stopped daily builds for focal.

[Shih-Yuan Lee (fourdollars)]

There are some OEM images on focal for few platforms that we are still working on.
It is nice to have ubiquity updates on focal.

[Andreas Hasenack (ahasenack)]

There is a ubiquity package in focal-proposed, version 20.04.15.20[1]:

ubiquity (20.04.15.20) focal; urgency=medium

  * Automatic update of included source packages: shim-signed 1.40.9.

 -- Graham Inggs <email address hidden> Tue, 14 Mar 2023 11:56:03 +0000

This change is not in the upstream focal branch for this project[2], where the latest version is:

ubiquity (20.04.15.19) focal; urgency=medium

  * Backport the ability to unhide passwords that are being typed-in during
    various stages of the installation (LP: #1960306).
  * Automatic update of included source packages: partman-auto
    134ubuntu13.1 (LP: #1959971).

I'd rather not merge https://code.launchpad.net/~fourdollars/ubiquity/+git/ubiquity/+merge/426347 until that is sorted.

Hello Shih-Yuan, or anyone else affected,

Accepted ubiquity into jammy-proposed. The package will build now and be available at https://launchpad.net/ubuntu/+source/ubiquity/22.04.20 in a few hours, and then in the -proposed repository.

Please help us by testing this new package. See https://wiki.ubuntu.com/Testing/EnableProposed for documentation on how to enable and use -proposed. Your feedback will aid us getting this update out to other Ubuntu users.

If this package fixes the bug for you, please add a comment to this bug, mentioning the version of the package you tested, what testing has been performed on the package and change the tag from verification-needed-jammy to verification-done-jammy. If it does not fix the bug for you, please add a comment stating that, and change the tag to verification-failed-jammy. In either case, without details of your testing we will not be able to proceed.

Further information regarding the verification process can be found at https://wiki.ubuntu.com/QATeam/PerformingSRUVerification . Thank you in advance for helping!

N.B. The updated package will be released to -updates after the bug(s) fixed by this package have been verified and the package has been in -proposed for a minimum of 7 days.

I don't see anything to do here for sponsors, so I am unsubscribing sponsors. An upload has been uploaded for jammy and there's outstanding questions for focal that have not been addressed in this bug.

[Kai-Chuan Hsieh (kchsieh)]

Install Dell oem image on Latitude 7330 Rugged Extreme with ubiquity 22.04.20.

After installation:
1. $ sudo apt update
2. $ sudo apt install debsums
3. $ sudo debsums -c

No `debsums -c` returns the error of /sbin/start-stop-daemon popped.

  * Whenever removing packages, use apt-get autoremove --purge instead of
    apt-get purge so that no-longer-used dependencies are removed together
    with the package in question, and we do not leave behind any packages
    that will be reported as autoremovable later. LP: #1925265.
  * bin/oem-config-remove-gtk uses aptdaemon to remove packages, not
    apt-get. Set the flag to autoremove dependencies here as well.

  [ Nick Rosbrook ]
  * tests: modify test_city_entry to adapt to tzdata update (LP: #2022965)

  [ Shih-Yuan Lee (FourDollars) ]
  * Use dpkg-divert /sbin/start-stop-daemon unconditionally instead of just

The verification of the Stable Release Update for ubiquity has completed successfully and the package is now being released to -updates. Subsequently, the Ubuntu Stable Release Updates Team is being unsubscribed and will not receive messages about this bug report. In the event that you encounter a regression using the package from -updates please report a new bug using ubuntu-bug and tag the bug report regression-update so we can easily find any regressions.
