And now for the latest update.

I managed to install an extra couple of packages, before I stupidly
tried to do a system update.

Part of the system update (from the iso version of the installation)
involved a new kernel version, which, without the PAE patch being
inbuilt into the new kernel, broke the update and broke the Ubuntu
Software Centre.

So, the system apparently can not be updated, and, now, no more
packages can be installed, due to the lack of a PAE patch being built
into the kernel.

So, I guess that I now have to overturn the apparent success of the
installation, with the reiteration that the operating system is
apparently incompatible with Intel Celeron CPU's, due to the lack of a
patch to fix the PAE problem, being built into the kernel, as if the
system can not undergo security updates and bugfixes, then it can not
be regarded as reasonably secure or stable.
