Title:
  Installing libudev1 on a new Jammy installation uninstalls many
  packages.

Status in apt package in Ubuntu:
  In Progress
Status in apt source package in Jammy:
  Confirmed
Status in apt source package in Kinetic:
  In Progress

Bug description:
  On an Ubuntu 22.04 desktop system created using the current
  installation image without enabling package updates over the network,
  installing the package libudev1 results in a large number of critical
  packages being removed and rendering the system essentially unusable.

  https://github.com/tfoote/udevdebug/blob/main/Dockerfile is a Dockerfile which also demonstrates the issue.
  Building the image, which will install udev 249.11-0ubuntu3 and init 1.62, and then running `apt install libudev1` in the generated image results in

  The following packages will be REMOVED:
    libnss-systemd libpam-systemd systemd-timesyncd udev
  The following packages will be upgraded:
    libudev1

  
  This is completely prevented by ensuring that updates are installed from the jammy-updates repository before installing any additional packages and that is almost certainly the correct thing to do. But this is a punishing result for such a mistake.

  I would expect the installation to either force the upgrade of the
  other systemd packages or refuse to install libudev1 at the incorrect
  version relative to the other systemd packages until the system is
  upgraded.

  We found this out via a user report for ROS 2 Humble which is
  releasing on top of Ubuntu 22.04 next week:
