Upgrade Ubuntu 11.04

Question

I've a question about upgrading my old Ubuntu 11.04 to the latest version. How can I do this without loosing my settings and data?

Answer 1

Since Ubuntu 11.04 release has reached "End of Life", it could take additional steps to upgrade. Ubuntu Documentation has article describing the process:

• https://help.ubuntu.com/community/EOLUpgrades

The steps are:

1. Determine if backup required (and make one) if things go wrong.

2. Make sure you have the following lines at /etc/apt/sources.list:

   deb http://old-releases.ubuntu.com/ubuntu/ natty main restricted universe multiverse

   deb http://old-releases.ubuntu.com/ubuntu/ natty-updates main restricted universe multiverse

   deb http://old-releases.ubuntu.com/ubuntu/ natty-security main restricted universe multiverse

3. Update the package list and upgrade all the installed packages:

   sudo aptitude update && sudo aptitude safe-upgrade

4. Perform the release upgrade:

   sudo do-release-upgrade

Answer 2

Please using the below command and check the new update available for upgrade,

lsb_release -a

After checking the update, try with the below commands and upgrade the ubuntu to latest version,

 sudo apt-get update

 sudo apt-get dist-upgrade

Hope this helps.
