Hi Nio,
Thanks for the prompt response. I checked out the linked threads and my
conclusion is that most of the advice offered actually addresses the
converse of my problem. There are solutions to the question "How do I
introduce a new application package offline to an existing installed
distro. I read them with interest, this is also a problem I sometimes
face, but what is really on my mind is this:
How do I overwrite an existing full working installation's system files,
including the Linux kernel, with an upgrade to a more recent version (from
12.04 to 14.04 in this instance)? Specifically, I have the entirety of the
new version as released in an iso on a bootable DVD already; I have run
that iso live from the DVD and am satisfied that it's fine, apart perhaps
for a few regular-type dsriable updates which I will anyway do via
Lubuntu's Update Manager in due course.
What I would love to be able to do is boot from the new DVD and invoke the
live installer, selecting then the (currently non-existent) option to
overwrite the existing system including kernel, system executables,
scripts, configuration files, and distro-standard included application
packages that are more recent than ones I have already installed over the
older distro, without being forced to reformat the entire Lubuntu
partition, thereby losing all my painfully selected, downloaded and
installed additional application packages not to mention the gigabytes of
user data.
To preserve these important to me things I am currently forced to backup
everything that I think will be endangered, do a clean install of the new
Lubuntu, then restore everything from backup, in the process probably
overwriting some important new files that were installed with the new
version of the distro. A job stretching over probably 2 or 3 days
initially, followed unpleasant random discoveries at various (critical?)
points.
The only remotely relevant suggestion I could find would mean doing a
clean live install of e.g. Lubuntu 14.o4 on another machine booted from
the new DVD, then copy them into the named special directory on my
operational laptop's operational partition, then do a "no-download"
installation from that directory. I expect that will avoid the feared
non-optional reformatting requirement of the target partition, since the
named directory is on that partition?
The obvious potential problem here is that the interim machine on which
the clean install is done, may have subtle differences at the hardware or
BIOS level and thus force a clean installation that might be somewhat
inappropriate for the eventual operational machine.
Variations on this theme which might be better would include setting aside
a bootable partition on the operational target machine for the interim
clean install, then doing the copy at HDU speeds into the named directory
in the target operational partition, alternatively (and better for
propagation across a small family of computers needing the same upgrade)
doing the interim clean installation onto a bootable memory stick mounted
in the operational target machine, then copying back as before.
Any comments?
Best regards to all,
Basil

Hi Basil,
Maybe these links to the Ubuntu Forum will help you with a method for
offline package installation

So basically,
*Carry the program packages*
- go to a computer with fast and cheap internet connection and download
the packages you want,
- carry them to your own computer and
- copy them into the correct place
- install the package you want with the option --no-download
Best regards

OK, now to reveal the depths of my ignorance...
I am at last ready to update my own Lenovo's Lubuntu 12.04 LTS as
numerously updated (now at .67 or .68, I think) to 14.04 with the
initial deal-inhibitors sorted. I have a bootable DVD with the 14.04 iso
which performs adequately in live test mode and want to do the
update/upgrade from the DVD, being in the unhappy position of having to
pay for every byte that is downloaded. (And I don't have a hardwired
internet connection).
