 raitobezarius (DECT: 7248) | supposedly | 14:50:00 |
| raitobezarius (DECT: 7248) | but actually the interface contain only IPv6 | 14:50:07 |
| raitobezarius (DECT: 7248) | but the nameserver contain IPv4 only | 14:50:14 |
| raitobezarius (DECT: 7248) | nameserver 169.254.1.1 namely | 14:50:21 |

Also the thing that failed is a FOD I think? golang dependencies | 14:50:56 |
| raitobezarius (DECT: 7248) | (so yes) | 14:51:01 |

nameserver 169.254.1.1 namely … which I presume pasta translates to 127.0.0.1, which does not work because resolved is listening on 127.0.0.53? | 14:52:06 |
| raitobezarius (DECT: 7248) | well, your interface doesn't have 169.254.1.1 on eth0 | 14:52:30 |
| raitobezarius (DECT: 7248) | so it's immediately an ENETUNREACH | 14:52:34 |
| raitobezarius (DECT: 7248) | if your interface had 169.254.1.1, maybe there would be a chance because resolved is listening on 127.0.0.1 as well IIRC? | 14:52:57 |
| aloisw | hmm it does seem to have here?

| raitobezarius (DECT: 7248) | what is your ip a ? | 15:02:01 |
| raitobezarius (DECT: 7248) | on the host? | 15:02:02 |
| raitobezarius (DECT: 7248) | i mean | 15:02:12 |
| raitobezarius (DECT: 7248) | do you have ipv4 connectivity on the host? | 15:02:16 |

(ipv4 comes from there) | 15:02:54 |
| aloisw | Ah that might do it, I do have ipv4 on the host. | 15:03:06 |
| aloisw | Right, removing all IPv4 addresses (except 127.0.0.1/8 on lo) makes IPv4 connectivity go away in the sandbox too. | 15:05:29 |
| raitobezarius (DECT: 7248) | which makes sense to some extent | 15:06:25 |
| raitobezarius (DECT: 7248) | but creates that very funny situation | 15:06:29 |
| raitobezarius (DECT: 7248) | where IPv4-only localhost services are now unreachable | 15:06:39 |
| raitobezarius (DECT: 7248) | a workaround is to always add 169.254.1.1 to lo | 15:06:53 |
| raitobezarius (DECT: 7248) | alternatively pasta could heuristically recognize NAT64 prefixes and do the right thing | 15:07:40 |
| raitobezarius (DECT: 7248) | not so sure this is a good idea | 15:07:45 |

a workaround is to always add 169.254.1.1 to lo The arguments passed to pasta are not different, so this seems like a pasta issue? | 15:08:37 |
| raitobezarius (DECT: 7248) | yep | 15:11:50 |
