[ubuntu-za] Is it worth it?

[William Walter Kinghorn]

Hi David,

I agree with Jonathan, if you want to go 9.10

But, considering that you don't re-install / upgrade every version, I would suggest that you hang on till 10.04 LTS version, and install from scratch,  and only stick with LTS versions

LTS version are every 2 years, and you can upgrade from LTS to LTS

Some people find that upgrading does not always work, so you must always backup your data before doing anything like upgrading

If you stay in the Durban area, I might have the repos for 9.04, I also have the repos for 9.10, or find someone in your area that has the repos

Basically, to upgrade, what is needed, is to link my HD to your PC, change sources.list to link to my 9.04 repo, type 1 or 2 commands and then wait until upgraded to 9.04, and then repeat for 9.10,  change sources.list to link to my 9.10 repo, type 1 or 2 commands and then wait until upgraded to 9.10. Like I said above, Some people find that upgrading does not always work, so you might have to install from scratch if the upgrade does not work

Another thing, if you have packages that are not in the repos, eg stuff that you have downloaded that has a deb package that you installed or stuff that you have compiled, these will not be upgraded

The discs from ShipIt are not for upgrading your systems - they are
for installing from scratch.  They contain squashed live ready-made
base systems which give you a fresh installation almost instantly,
with a few minor bits of configuration.

In addition, you can't (or rather, shouldn't) skip versions when
upgrading.  To get from 8.10 to 9.10, you should first upgrade to
9.04, and from there to 9.10. Each new version knows exactly what
needs to happen to the previous version to get itself up and running.
It would be a lot harder to make generic instructions that would work
when coming from *any* previous version, so the sensible thing to do
is to leapfrog up versions, making each change as they come.

Upgrading your system to the next version is essentially a matter of
upgrading each package installed on the system to the level at which
the next distribution version has them.  This is why the ShipIt discs
can't upgrade them:  they don't contain all the packages which you
have installed (and there's no way they could - they can't tell what
you've installed).

My recommendation is that you take a copy of your /etc, and keep your
/home, and install 9.10 fresh, but using your old /home (thus keeping
all your files and settings).  In addition, before you upgrade, you
can take a list of the packages you have installed and install them on
the new system once you've upgraded.  To do this, run:
   dpkg --get-selections > ~/installed-files-8.10

Once you've upgraded, run:
   dpkg --set-selections < ~/installed-files-8.10

And then run "aptitude install" to make the changes happen.
