			<syntaxhighlight lang="bash">
			sudo resize2fs /dev/ubuntu-vg/ubuntu-lv
			df -h

			Next, let's get the latest updates for the server and remove any space wasters.

			<syntaxhighlight lang="bash">
			sudo apt update && sudo apt -y upgrade && sudo apt -y autoremove

Now we need to configure the timezone and our charset. If you want to enable unattended upgrades, now is a good time to do that as well.

	<~~code~~>sudo ~~resize2fs /dev/ubuntu~~-vg/~~ubuntu-lv~~		<syntaxhighlight lang="bash">
			sudo dpkg-reconfigure tzdata && locale-gen en_US.UTF-8 && dpkg-reconfigure locales && dpkg-reconfigure -plow unattended-upgrades

	After you've finished installing the OS, it's time to connect to the server and begin updates and a base configuration. I connect through SSH, but you can do it the physical box if you want. I've found that if you don't make any changes to the default disk settings, you fill up the disk very quickly. Let's change that first, we need to resize the logical volume to use all the existing and free space of the volume group.
