uvtool example missing sudo or root

[Nivedita Singhvi]

On the following webpage:

https://help.ubuntu.com/lts/serverguide/cloud-images-and-uvtool.html
"Ubuntu 18.04 » Ubuntu Server Guide » Virtualization » "

are instructions for installing and using uvtool,
with the first instruction showing the apt cmd
to get the package:

$ apt -y install uvtool

It needs to be either:

$ sudo apt -y install uvtool

or

# apt -y install uvtool

to alert the user to the fact the command needs sudo
or root privs.

As is, this is the output they would see:

$ apt -y install uvtool
E: Could not open lock file /var/lib/dpkg/lock - open (13: Permission denied)
E: Unable to lock the administration directory (/var/lib/dpkg/), are you root?

Yes, of course. Thanks.
