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

Status in apt source package in Jammy:

Bug description:
[Impact]
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.
[Test plan]
Comprehensive regression test suite validating a full solver dump with the
issue is run as autopkgtest.
[Where problems could occur]
We could break other things from resolving. The solver is a bit finicky.
Hopefully this is isolated enough.
[Other info]
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:
