[SOLVED] Container won't run in a pure cgroupv2 environment!

[sdfsdfsfgdsgthgth]

Hello. Have VE 7.4.17 updated from V6. I can SSH into OS and web is accesible.
One of containers with older Linux shows this problem:
WARN: old systemd (< v232) detected, container won't run in a pure cgroupv2 environment! Please see documentation -> container -> cgroup version.
TASK WARNINGS: 1Tried to connect to proxmox via SSH an use "systemd.unified_cgroup_hierarchy=0"

But it shows only: -bash: systemd.unified_cgroup_hierarchy=0: command not found

Please help?
