I have this error when im trying to uprade my image I had the vyos-rolling-latest.iso and I want to upgrade to vyos-1.4-rolling-202301300918-amd64.iso

set system name-server


I tried it but it does not work

Do you use IPv6?
Could you check if you have routes to configured name-servers and you can ping nameservers

You don’t even have a default route.
We discuss it in another topic.
