[Bug 1978931] Re: `debsums -c` returns the error of /sbin/start-stop-daemon

[Robie Basak]

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.

** Changed in: ubiquity (Ubuntu Jammy)

Bug description:
  [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.
