Ubuntu upgrade from release 10.04 to 12.04

Asked by sibivel on 2012-04-30

I am a beginner in Ubuntu. If I open my update manger, it is showing that "New ubuntu release 10.10 is available" but, I need to upgrade to still latest version like 11.10 or 12.04 LTS. Please suggest me a way. Thanks.

First back up everything you have by way of data, bookmarks e-mail address book etc. If you back up your entire home folder including hidden files you should be safe. This is because problems may occur during the upgrade process which are hardware related, or due to power failure etc. My preference would be to use a freshly downloaded live CD and install or upgrade from there. Actually, I always do a clean install and then restore my data. If you are using Firefox as your browser, set it up to save your bookmarks to the Firefox cloud and make sure you print out the access key. If your data is not enormous, you could sync all your files to Ubuntu one ....

Upgrade is a major process not like update. If you upgrade, you will need first of all to update to 10.10, then 11.04 and so on. Every stage will take forever and will present some risk of data loss, so my answer is to get 12.04 which is fantastic! Try running it from the live-CD to make sure you like it, then do a clean install and restore all your data. Believe me, it will save you a lot of time and maybe some aggravation.

You can also upgrade 10.04 LTS directly to 12.04 LTS ...

In update-manager options please choose to upgrade only to LTS release... then press verify...

But read the release note here:


so please follow the Barry Drake answer...
