Installation failed

My installation on a Raspberry Pi with Ubuntu 20 failed, here is the result:

TASK [common : Check size of MTU] ********************************************** fatal: [localhost]: FAILED! => {"msg": "The task includes an option with an undefined variable. The error was: 'dict object' has no attribute 'mtu'\n\nThe error appears to be in '/algo/roles/common/tasks/facts.yml': line 17, column 3, but may\nbe elsewhere in the file depending on the exact syntax problem.\n\nThe offending line appears to be:\n\n\n- name: Check size of MTU\n ^ here\n"} included: /algo/playbooks/rescue.yml for localhost

I choose ubuntu server with the ip "localhost" and then I put the public IPv6.
What's wrong ?

I think Algo only supports connecting to a server over IPv4. Does the system have an IPv4 address? The code that's failing is attempting to check the MTU of the default IPv4 interface.

No it only has ipv6
