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

[Sam Lane]

When creating the Ubuntu Budgie Pi image, we ran into this same issue.
The packages are removed through /usr/sbin/oem-config-remove-gtk but
leave behind these same packages. If we mount and chroot into the image,
and modify oem-config-remove-gtk and change:

    def _on_transaction(trans):
        apt_dialog = AptProgressDialog(trans)
        ...

to:

    def _on_transaction(trans):
        trans.set_remove_obsoleted_depends(remove_obsoleted_depends=True)
        apt_dialog = AptProgressDialog(trans)

this seems to "fix" the issue. After setup, there are no packages to
autoremove. I have tested this not only on our Budgie Kinetic Pi image,
but also on the Ubuntu Kinetic RasPi Preinstalled Desktop image.

Bug description:
  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

  After this operation, 45.5 MB disk space will be freed.

  Abort.

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