systemd Cannot add dependency job for unit cgmanager.service and display-manager.service

Hi, upgrade to the new Virtual Environment 4.4-12/e71b7a74 version and noticed those fail warnings in the system log, should I be worried of those? Not sure if those exists in the old version.

Hi,

For cgmanager there is no need to worry, we do not need it anymore and it should get removed by a

apt-get autoremove

Or use:

apt remove cgmanager

This can be seen as systemd noise, its graphical target has a dependency on display-manager.service which would be provided by a desktop environment, which on a Proxmox VE server normally does not exists.
If it really annoys you you could open
/lib/systemd/system/graphical.target
and remove the

Wants=display-manager.service

line.

But both are not causing any harm.
