Upgraded from 16.04 to 18.04 today and want to start using netplan, but it doesn't appear to be installed? I tried to install it with
apt install netplan but none of the files/directories listed on the Migrating to Netplan page exist.
Netplan is shipped in the
netplan.io package. Running
apt install netplan.io will give you the /etc/netplan directory; you will need to provide your own config files in this directory, with a .yaml extension.
netplan.io package was not installed for you on upgrade from Ubuntu 16.04 to Ubuntu 18.04, then it appears you are missing the
ubuntu-minimal package. It is recommended that you install this package to ensure you have the standard Ubuntu experience.
