** Description changed: + [Impact] + + This bug prevents users on Impish and newer from connecting to Focal + systemd containers using `machinectl shell`. 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.
