the scaleway box have been having various issues, defined in the parent ticket (legacy/trac#32920). after much messing around with upstream, they finally threw the towel: > Following further investigation, we did not notice any issue on our side that could explain your system booting on a different OS, nor Rescue mode. > All we can suggest is to create a new server if you are not able to access your personal environment anymore I'm afraid. In other words, the box (scw-arm-ams-01) is lost with all hands. Given this is a build box, I do not believe it is worth restoring and we should just complete the decomissionning process. It was running a `aarch64` architecture, according to Puppet facts, and we already have a replacement for his at Linaro.
