Binary package “liblwp-online-perl” in ubuntu bionic

module to check if there is Internet access

 LWP::Online will try to verify, as accurately as it can, if the
 host has any Internet access: it will check if there is basic
 network access, DNS connectivity and it will also check whether
 one from a whole set of transport (HTTP, HTTPS, FTP, and so on) is
 actually available.
 The exported 'online' function can also be used by other modules to
 skip the tests which require Internet connectivity.
