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:
x
# Check your current DNS settings in /etc/resolv.confcat /etc/resolv.conf# Install resolveconf and set 8.8.8.8 as primary DNS serversudo apt updatesudo apt install resolvconfecho 'nameserver 8.8.8.8' | sudo tee /etc/resolvconf/resolv.conf.d/head# Update /etc/resolv.conf using resolveconfsudo resolvconf -u# Check the updated DNS settings cat /etc/resolv.confIf everything went well, you should see something like this (8.8.8.8 should be the first nameserver in the list):
nameserver 8.8.8.8nameserver 127.0.0.53options edns0 trust-adPlease 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.confSee this guide for more information: How To Set Permanent DNS Nameservers in Ubuntu and Debian
