IDEasy can not install docker on arch linux

[jan-vcapgemini]

Actual behavior

When I try to install/run docker using ide docker I get the following exception:

<username>@archlinux:~/projects/kubernetes/workspaces/main$ ide docker
Couldn't get installed version of docker
We need to run the following privileged command(s):
curl -s https://download.opensuse.org/repositories/isv:/Rancher:/stable/deb/Release.key | gpg --dearmor | sudo dd status=none of=/usr/share/keyrings/isv-rancher-stable-archive-keyring.gpg
echo 'deb [signed-by=/usr/share/keyrings/isv-rancher-stable-archive-keyring.gpg] https://download.opensuse.org/repositories/isv:/Rancher:/stable/deb/ ./' | sudo dd status=none of=/etc/apt/sources.list.d/isv-rancher-stable.list
sudo apt update
sudo apt install -y --allow-downgrades rancher-desktop=1.22.3*
This will require root permissions!

Error: IDEasy failed with exit code 255

When I then manually install Rancher Desktop using the AppImage f.e. and run ide kubectl I still get the installation procedure for docker even though kubectl is already globally installed.

<username>@archlinux:~/projects/kubernetes$ ide kubectl
