[Bug 1925265] Re: Fresh install of kinetic-preinstalled-desktop-arm64+raspi has packages to autoremove

[Dave Jones]

Verification done on daily jammy pre-installed desktop image. After oem-
config has completed, after first login, I attempted apt autoremove and
got the following output:

dave at miss-piggy:~$ sudo apt autoremove
Reading package lists... Done
Building dependency tree... Done
Reading state information... Done
0 to upgrade, 0 to newly install, 0 to remove and 5 not to upgrade.

Bug description:
  [Impact]

  Immediately after installing hirsute-preinstalled-desktop-arm64+raspi
  on a Raspberry Pi I noticed that there were packages available for
  autoremoval.

  bdmurray at bdmurray-desktop:~$ sudo apt autoremove
  [sudo] password for bdmurray:
  Reading package lists... Done
  Building dependency tree... Done
  Reading state information... Done
  The following packages will be REMOVED:
    cryptsetup-bin dctrl-tools dmeventd dmraid dpkg-repack efibootmgr gir1.2-timezonemap-1.0 gir1.2-xkl-1.0 grub-common grub-efi-arm64
    grub-efi-arm64-bin grub-efi-arm64-signed grub2-common kpartx kpartx-boot libdebian-installer4 libdevmapper-event1.02.1
    libdmraid1.0.0.rc16 liblvm2cmd2.03 libtimezonemap-data libtimezonemap1 lvm2 os-prober python3-icu python3-pam rdate
    thin-provisioning-tools
  0 upgraded, 0 newly installed, 27 to remove and 0 not upgraded.
  After this operation, 45.5 MB disk space will be freed.
  Do you want to continue? [Y/n] n
  Abort.

  It seems to me the installation process should run an autoremove at
  the end.

  bdmurray at bdmurray-desktop:~$ cat /var/log/installer/version
  ubiquity 21.04.19

  [Test case]
  * Wait for a daily jammy preinstalled image to be built after ubiquity is accepted and built.
  * Install using the image.
  * Confirm that after installation, 'sudo apt autoremove' does not offer to remove any additional packages.

  [Where things could go wrong]
  Because we are now removing additional packages from the system that previously were left installed at the end of oem-config, it is possible that for some installations using oem-config - but *not* the raspi preinstalled images - that some of the packages being removed are needed to access the disk and that removal will break the boot.  The correct fix in such a case is to make sure the relevant packages are marked manually installed as part of the installation process; we already do this, but because of this bug with removals it could be that this isn't being done correctly in all cases which would only be discovered after fixing this bug.  We should handle that by making any necessary follow-up fixes to ubiquity.
