Hi @Sgilk , thank you for your response. I think i managed to install the ctrlX Automation SDK on my ubuntu machine by following these steps: Downloading the repository as a zip file and unzipped it Installed the required packages (install-required-packages.sh) Installed snapcraft (install-snapcraft.sh) Cloned and installed the ctrlX AUTOMATION SDK (clone-install-sdk.sh) I think this step is bit duplicated, since i already downloaded the SDK as a zip archive. I think this script does more than just cloning the repository I can build the Cpp-sample snaps on my machine now. 😀 But only if i call the build-snap-amd64.sh script with sudo and i need to define where it can find snapcraft: sudo env "PATH=$PATH" ./build-snap-amd64.sh Error without sudo: ./build-snap-amd64.sh Error if i don´t define where to find snapcraft: sudo ./build-snap-amd64.sh Am i missing something or is it really necessary to use sudo to build the snaps? I want to also add a view hints what didn´t work: In the VirtualBox setup page in chapter "Setup Standard Packages" there is the information to install packages manually according to the user-data-img file. i searched in all user-data-img files for these packages but i couldn´t find any (packages: - zip - unzip). https://boschrexroth.github.io/ctrlx-automation-sdk/setup_windows_virtualbox_ubuntu.html On this page Important Installation Scripts is a script listed named install-sdk.sh. I can´t find this script in the repository https://boschrexroth.github.io/ctrlx-automation-sdk/install-scripts.html
