I'm going to install a fresh Ubuntu 10.04 (LTS), supported until April 2013. My question is about the upgrade to the new LTS version, and in particular I'd like to know which best practices I have to adopt to reduce potential upgrade issues when 12.04 will be released.

For example, don't install packages from unofficial repositories, etc.

I'll appreciate any thoughts on this. Thanks.

from what i know you have to upgrade from 10.04 to 10.10 to 11.04 and so on, i doubt that you can just upgrade from 10.04 to 12.04, issues may arise due to the changes that probably will take place, and it would be better to do a clean install of 12.04. – Uri Herrera May 19 '11 at 22:05
@Uri Excerpt from How can I upgrade to the latest version of Ubuntu?: "users of version 7.10 would first have to upgrade to version 8.04 before upgrading to version 8.10. An exception to this rule is with LTS (Long Term Support) releases. You can upgrade directly from the previous LTS release to the current release." – Paolo May 19 '11 at 22:16
oh nice, well then there's no problem, with ubuntu itself, the only downside is that you will have to stick with w/e stable software you have and wait until the next LTS to receive an upgrade, that includes drivers too. – Uri Herrera May 19 '11 at 22:21

The best advice I can think of is take measures so that, in case of any problem, you can go back to your old configuration while you work on fixing the problem.

In particular:

  • Backup your data
  • Keep your data in a different partition than the OS
  • Reserve a spare partition for the future distribution

The last bullet I think isn't very common, but I find it quite effective. What I do when I have to upgrade is avoid the upgrade procedure completely and just install the new distribution in a different partition while using the same partition for my home directory. This way, if the new distribution doesn't work for me, I can either look into the problem and try to fix it or, if I need to do some other thing, use the old distribution.

I've never had any serious problem; but, at the same time, I've always been sure that in case of any problem (drivers, configuration, etc.), I could go back and use my old stable configuration as usual without any danger to my personal files.
