[Bug 1980725] Re: bin:google_authorized_keys shipped by this package conflicts with the same binary shipped by src:google-compute-engine-oslogin

[Utkarsh Gupta]

Furthermore, since Impish is going to be EOL'd in two weeks, it's not
worth fixing it there at all because it'll take us at least sometime to
get this verified, et al, only to have Impish EOL'd so marking this as
Won't Fix.

Bug description:
  [Impact]
  ========

  The two packages src:google-compute-engine-oslogin and src:google-
  guest-agent cannot be co-installed together because they ship the same
  binary so dpkg throws the following error out:

  dpkg: error processing archive /tmp/apt-dpkg-install-USEDmn/2-google-guest-agent_20220622.00-0ubuntu1_amd64.deb (--unpack):
   trying to overwrite '/usr/bin/google_authorized_keys', which is also in package google-compute-engine-oslogin 20210907.00-0ubuntu2
  dpkg-deb: error: paste subprocess was killed by signal (Broken pipe)

  [Test Plan]
  ===========

  $ lxc launch images:ubuntu/kinetic ktemp
  $ lxc shell ktemp
  $ apt update
  $ apt install google-compute-engine-oslogin
  $ apt install google-guest-agent

  This should result in failure. Whilst these two should co-install
  together.

  Another thing to note is the file list that's going to be provided:
  Without fix:

  /lib/systemd/system/google-guest-agent.service
  /lib/systemd/system/google-shutdown-scripts.service
  /lib/systemd/system/google-startup-scripts.service
  /usr/bin/google_authorized_keys
  /usr/bin/google_guest_agent
  /usr/bin/google_metadata_script_runner
  /usr/share/doc/google-guest-agent/changelog.Debian.gz
  /usr/share/doc/google-guest-agent/copyright

  With the fix:

  /lib/systemd/system/google-guest-agent.service
  /lib/systemd/system/google-shutdown-scripts.service
  /lib/systemd/system/google-startup-scripts.service
  /usr/bin/google_guest_agent
  /usr/bin/google_metadata_script_runner
  /usr/share/doc/google-guest-agent/changelog.Debian.gz
  /usr/share/doc/google-guest-agent/copyright

  That is, the google_authorized_keys shouldn't be shipped.

  [Where Problems Could Occur]
  ============================

  Whilst this is totally broken in Kinetic and in the -proposed pocket
  of Jammy, Impish, and Focal, it can't get any worse than that. But an
  edge case might happen when the person has just installed google-
  guest-agent and started to use the binary from there, instead of using
  it from the original source (the oslogin package). But this hasn't
  been published in any stable releases so I don't see that happening,
  really. :)
