Install software for release x in release y

[Andysan]

Hi,

A simple question, but one that i can't find the answer to; if i want to install a particular application and it's only available for Ubuntu release 'y' (a later version than my version, version 'x') can i do so or will the universe fold in on itself (or equally bad, will stuff not work properly on my PC)?

Thanks!

It depends on the program. I've taken various Karmic pre-release packages and installed them in 9.04, 8.10, 8.04.2 without problems. You will usually be cautioned by apt-get or aptitude when installing packages that conflict or break others. Just to warn you now if something goes wrong, downgrading is a pain [when it's even possible] and usually results in a clean install anyway. Upgrade the software only if you need the new features it provides.

Thanks, that's a useful reply. I guess i'll be upgrading my ancient 8.04 boxes then!):P

Just to check, would the syntax in apt-get be:

sudo apt-get install -t karmic foo

to upgrade from foo version x which is on the jaunty repository to some later version which is in the karmic repository?

This syntax doesn't seem to be working... would anyone be able to set me straight? The package I'm trying to upgrade is subversion.
