Sofdpac running in a Ubuntu VM

[NascimentoOliveira]

I tried to use the runtime in a Linux environment and followed some tutorials and videos to do it. However, I keep receiving this error message: "Error response from daemon: failed to create task for container: failed to create shim task: OCI runtime create failed: runc create failed: unable to start container process: error during container init: error setting cgroup config for procHooks process: openat2 /sys/fs/cgroup/memory/docker/0e726bce685f5e2a3225ed9628df24a065b28cb2b999f9f33d9806c729843b56/memory.limit_in_bytes: no such file or directory: unknown"

I tried to start SoftdPAC by the EcoStruxure Automation Expert and I can discover the manager app running in Linux at the discovery in the Physical View. But when I configure and implement the configuration to start the softdPAC, it returns this error message. 

In the figures below, it is possible to see the versions used at the VM and the containers.

The sofdPAC version is 24.0.24178

Hi @NascimentoOliveira

Your issue is probably related to cGroups.

It seem that you're actually using Ubuntu 24.04 which is not actually officially supported for Softdpac_V24.0
The recommended version is Ubuntu 22.04 for the moment. 

As Softdpac_V24.0 currently force the usage of cgroupV1, your OS should support cgroupV1, which is probably not the case by default for Ubuntu 24.04.


The recommended solution is to use Ubuntu 22.04.
However, for temporary use case, you can use the following workaround to move to cgroupV2:

1. Uninstall Softdpac (you can use the official documentation)
   

   $ sudo python3 uninstall.py​

2. Edit the file 'install.py' and find the 2 lines 'systemd.unified_cgroup_hierarchy=0' and change =0 to =1
   
3. Re-install softdpac 
   

   $ sudo python3 install.py

4. If the device doesn't reboot after the installation, force the reboot
   

   $ sudo reboot​

Let me know if your issue is solved

Tried with Ubuntu 22.04, and it solved the problem. Thanks
