You have this message because

Unable to determine the host or domain name of your computer.
Setting it to localhost.localdomain
Unable to resolve host name.
Please specify the host name in the /etc/hosts file
or specify DNS configuration in the /etc/resolv.conf file on your system.

you can fix this problem like this
pico /etc/hosts

you may see only
88.198.201.210 ubuntu

and you must add this line
127.0.0.1 localhost.localdomain localhost
