Okay… per all the above clues I finally fixed this on my Ubuntu 22.04 system (upgraded from 20.04).

It was a CGROUP2 bug/problem so I disabled “cgroup2” use on the HOST and now things work and all the containers startup Ok.

Work-around Solution was:

add the following string to the GRUB_CMDLINE_LINUX line in /etc/default/grub and then run sudo update-grub.

systemd.unified_cgroup_hierarchy=0

It still begs the question why clean Installs of Ubuntu 22.04 LTS work correctly but “Upgrades” from 20.04LTS to 22.04LTS break something with CGROUP2 ?
