Hi all,
I was trying to install Docker following the pro instruction when I got this error:

Err:1 http://archive.ubuntu.com/ubuntu xenial InRelease
Temporary failure resolving 'archive.ubuntu.com'
Err:2 http://security.ubuntu.com/ubuntu xenial-security InRelease
Temporary failure resolving 'security.ubuntu.com'
Err:3 http://ppa.launchpad.net/ansible/ansible/ubuntu xenial InRelease
Temporary failure resolving 'ppa.launchpad.net'

Obviously, my dns works:

root@eve-ng:~# nslookup security.ubuntu.com
Server: 8.8.8.8
Address: 8.8.8.8#53

Non-authoritative answer:
Name: security.ubuntu.com
Address: 91.189.91.23
Name: security.ubuntu.com
Address: 91.189.91.26
Name: security.ubuntu.com
Address: 91.189.88.162
Name: security.ubuntu.com
Address: 91.189.88.152
Name: security.ubuntu.com
Address: 91.189.88.149
Name: security.ubuntu.com
Address: 91.189.88.161


Any idea?

PS: apt-get update from console works fine too

Ok, I have resolved this issue rebooting the box a couple of times.
Now I have a different issue shown at the end of “apt-get install eve-ng-dockers“:
