Since you confirmed openssh-server is installed, the issue is almost certainly a configuration block or a systemd conflict specific to Ubuntu 22.04 LXC templates. Follow these steps from the container's console:

1. Enable Root Login -> Ubuntu 22.04 blocks root login by default.

Edit the config:

nano /etc/ssh/sshd_config

Find the line:

#PermitRootLogin prohibit-password

Change it to:

PermitRootLogin yes

Save and exit (Ctrl+O, Enter, Ctrl+X).
