nmcli fails to set method to "disabled" or "ignore" for ipv6 when ipv6 addresses already exist in the config

tlskinneriv commented 6 days ago

Summary

When setting the method for IPv6 to "disabled" or "ignore", and there are IPv6 addresses already defined in the config, the module cannot set the new method. May need to have a condition to remove the addresses from the config before setting the method to allow this to work properly. This may extend past addresses and include gateway or routes as well, but I have not performed any additional testing. This may also extend to IPv4 method setting to "disabled" as well.

Steps to Reproduce

- name: Set an ipv6 address
  community.general.nmcli:
    conn_name: ens192
    ip6: "::1"
    state: present

- name: Set ipv6 method to disabled
  community.general.nmcli:
    conn_name: ens192
    method6: disabled
    state: present

Expected Results

ipv6.method to be set to "disabled" or "ignore" successfully. If the connection has existing ipv6 addresses configured, they would be removed.

Actual Results

Error: Failed to modify connection 'ens192': ipv6.addresses: this property is not allowed for 'method=disabled'\n
Error: Failed to modify connection 'ens192': ipv6.addresses: this property is not allowed for 'method=ignore'\n
