I've been running an Ubuntu desktop for a couple of years. I regularly update the security and recommended updates via Upgrade Manager. However it seems I didn't have Upgrade Manager set up to tell me of Ubuntu updates. Having realised this post the April-2013 loss of support for 10.04, and changed the settings, it now offers me an upgrade to 10.10. However when clicking on it and following the upgrade instructions, I consistently get the following error message:

"Failed to fetch. Fetching the upgrade failed. There may be a network problem."

Now I don't necessarily want 10.10, and would prefer to skip to the latest one with the longest duration of support available, which appears to be 12.04 LTS.

Bearing in mind I have very few IT skills (Ubuntu was set up for me by an IT expert to temporarily replace a very slow running Windows Vista, but I loved it so stuck with it ever since):

  1. Can someone tell me how I can upgrade directly to 12.04 LTS?
  2. Is there any danger of losing existing files etc that I should be aware of in doing so?
  3. And - less importantly, but if anyone has time to explain - what exactly is the difference between supported and unsupported (ie. what would happen longer term if I just carried on using 10.04)?

Many thanks,

Tim.

  2. No. Always have a backup of course, but it should upgrade without problems.
  3. Support means you get security and other updates for your system. LTS (Long Term Supported) is supported for a longer period.

Recently Canonical reduced the support period for non-LTS to 9 months. But don't be afraid, it's perfectly stable, and you have plenty of time to roll with the next release when it comes out. And to be honest, your PC won't stop if you slip out of the support period. You can just catch up whenever you want.

Which one to use? It all depends on you. LTS is a bit "older", but it provides a long-term, stable environment for enterprise, and servers. The non-LTS version is stable too, but you may not want the upgrade hassle on a whole bunch of company servers every half a year.

For desktop, I go for the latest release.
For our company servers, I choose the LTS versions.
And for my own servers, I just run the latest release too.
