DNS and connectivity issues

If you encounter DNS or Internet connectivity issues during the Sandbox installation process, it is recommended to configure public DNS nameservers (e.g.: 8.8.8.8 or 1.1.1.1).

If you have a desktop installation, you may configure the DNS settings using the NetworkManager GUI.

If you have a server installation without a desktop environment, you can run the following commands:

# Check your current DNS settings in /etc/resolv.conf cat /etc/resolv.conf # Install resolveconf and set 8.8.8.8 as primary DNS server sudo apt update sudo apt install resolvconf echo 'nameserver 8.8.8.8' | sudo tee /etc/resolvconf/resolv.conf.d/head # Update /etc/resolv.conf using resolveconf sudo resolvconf -u # Check the updated DNS settings cat /etc/resolv.conf

If everything went well, you should see something like this (8.8.8.8 should be the first nameserver in the list):

nameserver 8.8.8.8 nameserver 127.0.0.53 options edns0 trust-ad

Please also check your DNS settings in a Docker container (8.8.8.8 should be the first nameserver):

sudo docker container run --rm busybox cat /etc/resolv.conf
