ipv6 broken on Ubuntu 20.04

I noticed last night my IPv6 configuration is borken on my Ubuntu 20.04 machine. It used to work before, I guess (but don’t know) it broke during an update.

Any idea how to re-enable it?

Hello there,

There could be a configuration problem. Looks like 50-cloud-init.yaml file using the same value for IPv6 address and IPv6 gateway. Could you please confirm whether you have updated the correct gateway for ipv6 and you will be able to find the ipv6 gateway on the droplet page of your DigitalOcean cloud panel?.

Once you have fixed that you will have to reboot the droplet and then try to ping6 again.

I hope this helps but feel free to write back if you have any concerns.
