I'm slightly confused as to why Chris thought this (Chris, are you watching
the list?).
I'm also confused because Ubuntu doesn't normally have an admin account as
such. Do you mean that when you added the accounts you only made one of them
an administrator? By default, (K)Ubuntu) uses sudo to carry out
administrative tasks and that option in the User dialogue simply adds the user
to the sudoers list.
In case you aren't aware of how this works, the default setup in Kubuntu (and
Ubuntu AFAIK) is that the first user is a made a sudoer and additional users
can optionally be added. Whenever a task arises that requires root
privileges, the user is required to enter *their* password. In practice this
means that any commands to be executed in bash that need root privileges have
to be prefixed with the command sudo (eg apt-get, etc) and tasks performed via
the desktop will normally pop up a dialogue asking for the password. So for
updates, the user will be prompted that there are updates ready and on
clicking on the icon in the Task Bar the process continues, providing that the
user is in the sudoers list.
If you don't want the second user to have root privileges, then there is no
solution to this other than to switch user to install the updates.

Is this a particularly large SSD? Normally the OS is installed on the (much
faster) SSD to improve performance and the users are put onto the (much
larger) traditional hard drive because they don't usually need that level of
performance to load and save their files, but they are likely to use up the
space on the SSD.
