DNS and connectivity issues

If you encounter DNS or Internet connectivity issues during the Filescan 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
