netplan seems to cause the issue, deeper investigation ongoing. Added a software conflict check for it to prevent installation failures: 7a2e35b

[ScIT-Raphael]

Added a new commit to support netplan configuration: 7f27d6c

Pending scripts: v-stop-firewall and v-update-firewall

And the installer script.

Fixed with the last few commits, added netplan support and proxmox/lxc detection.
