[Ubuntu] Updating a package (How to?)

[Alex Mandel]

So I got a little stuck here, 1st time trying to update a package with a
newer version. Specifically I was testing updating the Spatialite
packages in Karmic/Lucid/Sid etc from 2.3.0 to 2.3.1. (If I figure out
how to do it I plan to create a 2.4.0 now that it came out too)

I'm probably compounding the issues I have by trying to build for Jaunty
(Ideally I would love to build for Hardy too)

Following https://wiki.ubuntu.com/PackagingGuide/Complete I pulled the
dsc, source etc from the existing packages and substituted in the newer
source. After debuild -S, I uploaded to Launchpad but the build failed,
because proj and geos weren't available to the auto build tools. I tried
adding Ubuntugis as a repo for the online build and tried copying the
packages proj and geos to my ppa, but I'm not sure that brings libproj
and libgeos with them and those are listed in Ubuntugis directly.

I assume that if I upload the same package for Karmic that it will work.
But then how would I backport it for Jaunty.

On another route, I used prevu to backport the package but that only
makes a deb and you can't upload debs to Launchpad.

If someone wants to see my build
errorshttps://launchpad.net/~wildintellect/+archive/wildintellect

Any help to keep me from wandering in circles in appreciated.

Thanks,
Alex
