Can you check if you find any more details regarding that error in /var/log/foreman-maintain/ or /var/log/foreman-installer/ ?

Is the machine you’re restoring to a working Foreman server? That’s a pre-requisite to be able to restore a backup.

The code that’s failing for you essentially says “could not find a foreman-installer on your machine” (I agree the error handling could be better, but still…)
