In order to install updates & make system changes he must be a member of
the adm group. You can do this by adding him to the group:

$ sudo adduser <username> adm

You can of course change him from a 'Standard' user to 'Administrator'
using Settings|User Accounts.

Ubuntu has, once again, dumbed down the desktop to accomodate the 'do a
reinstall' folks... To get the old 'Users and Groups' application back:


With that you can manage the groups & users directly via the gui without
having to do a 'Standard' user to 'Administrator' without knowing what
that actually changed.
