Can't apt-get update, "temporary failure resolving mirrors.digitalocean.com".

DigitalOcean DNS Debian

Hey, I'm using a newly rebuilt Debian 9 image and I can't successfully execute apt-get update. I've seen several similar questions asked here, none helped me. I can ping to google.com or other websites, even mirrors.digitalocean.com; is present in my /etc/resolv.conf, but still, right after having rebuilt the droplet, ssh-ed into it and changed the root password, the command doesn't work.

Here's the exact error message I get:

root@whatever:~# apt-get update

Hi @oax9c

I'm not seeing a problem right now. Could you try again?
I'm trying from servers in NYC1, NYC3, FRA1 and AMS2, and all resolves correctly.
I have seen this one time before, but several months ago - I couldn't connect for 10min.

  • I'm in FRA1 and still getting the error. Perhaps I'll wait until tomorrow to see if anything changes...

    • @oax9c What do you get if you run this:

      dig mirrors.digitalocean.com A +short && dig mirrors.digitalocean.com AAAA +short

      I get the following from FRA1 (note that your order might differ):

      And I'm using these DNS servers on that server:

      nameserver 2001:4860:4860::8844
      nameserver 2001:4860:4860::8888
      • I can't execute this command since I cannot install any package; however trying this with Ubuntu 17.04 gave me these addresses, although in a different order.

        I also tried to apt-get update and install zsh in Ubuntu, it failed because of 404 errors...
