Mate would definitely fall in this category. (It is for this very reason that i don't upgrade every 6 months, and often skip a release or two.) However, all the settings of that software is still kept in the user home directory, so when you reinstalled the software, it should keep its configuration. Eg. if you use an email app other than Thunderbird, upon installing it after the upgrade, all your accounts and emails will be available again without having to configure it again. Problems can be expected, especially when using universe and multi-verse packages, since it does not necessarily go through the same rigorous testing before release. (For this reason I only upgrade 6 months after the release of a new version. Although it's nice to be cutting-edge, it does come with a risk (of being "cut"). Since Saucy, there is a useful app available in the PPAs which makes this process easier: Aptik. You can run it before the upgrade and it will record and save all the additional packages and PPA you have installed. If you run it again after the upgrade it allow you (to attempt) to restore all of those PPAs and packages again. In short, if you run a non-stock desktop, you need to be a bit more prudent when upgrading. Charl </body> </html>
