Per Engineering, the problem seems to be in the yum repository - puppet was not able to install ASM packages. This can be caused e.g. by strict firewall.
Our repository is added during the installation and is removed afterwards. The reason is that if users upgrade their station our packages are not upgraded. Our packages must also be configured with puppet and simple upgrade would most likely break the station. That's why we remove the repository after the installation. The repository is located here:
There are also dockers downloaded (from several sources) and the station is registered (on api.asm.ca.com).
