How should I fix this error?

Looks like your system doesn't support ipv6. What system and version are you using?
Maybe you can try commenting out ipv6 related lines

[dca00]

IPv6 is disabled on this Fedora 41.

Can nothing be done about that error?

[garywill]

try commenting out ipv6 related lines in script
