"dev-entrypoint.sh": executable file not found

[Camo1000]

Hello,
I'm trying to install Dawarich on a Ubuntu 24.04 VM for a couple of days. I have the following error message :
"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: exec: "dev-entrypoint.sh": executable file not found in $PATH: unknown

This error appears at the end of install process, or when trying to start  dawarich_app  or dawarich_sidekiq (both unhealhty) on Portainer.   I've been trying to install version 0.15.10  and 0.21.3 with same errors :(  Installed Docker is version 28.1.1 

Should I have more luck when installing Dawarich on a nas ?
Great thanks for your help.
Greetings to all.
