- Inside Terminal, execute the following command:
root@riyaniezt:~# /etc/init.d/network-manager restart Rather than invoking init scripts through /etc/init.d, use the service(8) utility, e.g. service network-manager restart Since the script you are attempting to invoke has been converted to an Upstart job, you may also use the stop(8) and then start(8) utilities, e.g. stop network-manager ; start network-manager. The restart(8) utility is also available. network-manager stop/waiting network-manager start/running, process 7444
