[11:06] <Hanumaan> what is the netplan in ubuntu-20.04? I have set /etc/network/interfaces but then "ip a" did not show ip address and when I have set netplan it showed .. what does it mean? 
[11:31] <slyon> Hanumaan: netplan.io is the replacement for ifupdown (e.g. /etc/network/interfaces) in ubuntu 20.04. You can read about it on the website. ifupdown is deprecated, but still available in the archive if you still want to use that
