Ubuntu

Ubuntu is a linux distribution derived from debian. It's a very nice plug&play OS with all features I need.

cat /etc/os-release

cat /etc/lsb-release

lsb_release -a

Show the currently installed version. os-release has most information.

Modfications made

The few things I needed to tweak are listed here.

DNS resolving

In bionic-beaver (release 18.04) in /etc/NetworkManager/NetworkManager.conf put the line set dns=default in the [main] section.

Since release 14 the NetworkManager by default starts dnsmasq that makes your system act as forwarding DNS-server (127.0.1.1 in /etc/resolv.conf). This local server sometimes is not working properly so disable it.

In /etc/NetworkManager/NetworkManager.conf comment out the line: "dns=dnsmasq" /etc/resolv.conf will now show the DNS-server(s) provided by DCHP (if you use that).
