For non rolling release like Ubuntu, I'm always confused on what to do after an upgrade. In a very short time 11.10 will be released. So I'm asking what to do after the upgrade.
The objective is to preserve the system as it was, taking advantage of the new features and the new versions of apps, but preserve the stability of the system, as get the same documents, ppa's, applications installed, and settings.
In case of upgrade using the update manager, what I should do after, in order to preserve the ppa's i had but updated for the new release? And what things should I do in general?
In case of a fresh install, with separate home partition that will not be touched or changed, what should I do, in order to get the ppa's as they were updated for the new version? How do I preserve all the settings and apps? And what general things I should do?
P.S. I'm not interested in the upgrade itself, it's the various actions to do after the upgrade on both occasions, fresh or not. It's about time to explain this aspect for new and old users.
