Status in apt package in Ubuntu: In Progress Status in apt source package in Jammy: New 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.
