System information

failed to detect that has information loaded into the MBR, it’s nice to be able to skip
modifying it. If this is the only operating system installed on your server, select Yes .
When the system has finished the install, you’ll be asked to remove any media in the
drives and to reboot the system by selecting Continue, at which point the installation
will be complete and the system will reboot.
Base system update
Now that we’ve completed installing Ubuntu Server, we need to perform a system
update with apt-get to make sure we have the latest packages installed. You’ll be pre-
sented with a login prompt where you’ll log in with the username and password you
created in the installer (e.g., asteriskpbx). Once logged in, run the following command:
$ sudo apt-get update
[sudo] password for asteriskpbx:
...
Reading package lists... Done
$ sudo apt-get upgrade
Reading state information... Done
...
Do you want to continue [Y/n]? y
The password that sudo wants is the password you just logged in with.
Press Enter when prompted to continue, at which point the latest package updates will
be installed. When complete, reboot the system for the changes to take effect as the
kernel has probably been updated.
$ sudo reboot
Congratulations! You’ve successfully installed and updated the base Ubuntu Server
system.
Enable NTP for accurate system time
Keeping accurate time is essential on your Asterisk system, both for maintaining accu-
rate call detail records as well as for synchronization with your other programs. You
don’t want the times of your voicemail notifications to be off by 10 or 20 minutes, as
this can lead to confusion and panic from those who might think their voicemail noti-
fication took too long to be delivered:
$ sudo apt-get install ntp
