I can't make comments about the regressions, however I tested the systemd (245.4-4ubuntu3.18) package in a focal container and confirm that solves this bug (connecting from a jammy host).

This limits users ability to manage containers spawned with systemd-nspawn. [Test Plan] On a Jammy host, do the following: * Install systemd-container and debootstrap if necessary: $ sudo apt install debootstrap systemd-container * Create a Focal filesystem for the container: $ sudo debootstrap --arch=<arch> focal /var/lib/containers/lp1959475/ * Launch the container: $ sudo systemd-nspawn -D /var/lib/containers/lp1959475/ --machine test-container * Inside the container, set a password for root and then exit: $ passwd # Enter password when prompted $ exit * Re-launch the container with -b option: $ sudo systemd-nspawn -D /var/lib/containers/lp1959475/ --machine test-container -b * In a separate terminal window, try to connect to the container: $ sudo machinectl shell test-container * Observe the "Connection to machine test-container terminated" error message. [Where problems could occur] The patch expands the case where the TERM variable is inherited from PID 1 when building an execution environment, e.g. for a container. If problems were to occur, it would be related to the value of TERM in environments forked off of PID 1. [Other Info] This bug occurs when trying to connect to a Focal container from e.g. a Jammy host. For SRU verification, the container should be Focal, and the host should be Jammy. The -proposed package should be installed in the Focal container. [Original Description] The command "machinectl shell" does not work in systemd 249.9-0ubuntu2: $ sudo machinectl shell ns-xxx Connected to machine ns-xxx. Press ^] three times within 1s to exit session. Connection to machine ns-xxx terminated.
