Starting container process caused: exec: "dktl": executable file not found

[ahzf]

I created a new Debian11 guest VM on a Debian11 kvm host and installed docker and docker compose within the VM.
Then I followed: https://getdkan.github.io/dkan-tools/#installation.html
I created to symlink for dktl in /use/bin/

The other docker images seem to work...

root@dkan:~/my_project# docker ps

But here I do not know why this happens. It seems, that the docker image does not find the dktl within the container... but why?

root@dkan:~/my_project# dktl init
