    First update to be sure you are fully up to date. Then do the upgrade.

    You can do it via terminal as well:-

    sudo do-release-upgrade -c (Checks whether a new release is available)

    If there is a new release available issue the command sudo do-release-upgrade to start the upgrade process

    Personally I have always done a clean install because I think there is less chance of something going wrong. However things may have improved in that regard.

    Let others share their views/experiences.

    Yes, I would think so. I did that to go from 11.04 to 11.10. But many people claim it may be less of a problem, once 12.04 is actually released and torrents are available, to download the iso by torrent and then make a live USB (or CD) and then do an install from there.

    Given the changes between 10.04 and 12.04, I'm not sure there's much point in trying to retain config settings.

    (I didn't see that maestro had replied ;) )

    you can do 3 things cet close distro update and wait for while ubuntu 10.04 LTS is supported for 2013 so you can wait atleast for 12.04.1 or 1-2 month atleast :rolleyes:

    by that time you can download and check 12.04 see stability ......etc make sure

    then if you 100% sure then backup and go for update

    or

    fresh install which is better choice less chances of being buggy

    also wait for mint 13 release it give you more options

    my linux mint 10 life time over i planning to go for linux mint 13 with cinnamon so i wait till realease and + week or so

    Yes, and I would do it on the console. Logout, press Ctl-Alt+F1, logon, and execute

    sudo service kdm stop

    or

    sudo service gdm stop

    (whatever you're using).

    And I would also rename several folders before executing the upgrade:

    mv .config .config_old
    mv .local .local_old
    mv .kde .kde_old
    mv .gnome .gnome_old
    mv .gnome2 .gnome2_old

    It takes some time to (selectively) copy the old settings to the newly created folders but I found during previous upgrades that it pays out to do it that way as you can avoid possible problems.

    Thank you for all your answers.If it was not your help I would have never started to use Linux :)
    This will be my first distribution upgrade from 10.04 to 12.04.
    First of all I will not rush and will wait a few months,next I will make a CD of 12.04 and make a back-up of my old files.
    Best choice seems a clean install.BUT since I have a separate Home Partition,while making the clean install I think it is better not to format the Home Partition.I checked home and there are many configuration files,so if I do not format that partition is there a chance of corrupting the new LTS installation.

    No, don't worry. What I wrote in the post above were only some cautionary measures since I had experienced some quirks in the past due to configuration files that were obviously not 100% compatible with new Gnome or KDE versions. But normally an upgrade should not cause too much trouble.

    Formatting an existing home partition is definitely not necessary.

    i installed the last LTS on my Mum's laptop and i checked with the update manager two days a go and it was already offering the new LTS. i think i run this command
    Code:
    sudo update-manager -d
    i would always wait at least a month, or so before doing the upgrade in case there are any horrible bugs you'd want to avoid.

    having said that, i have never had a problem upgrading to new releases in the many years i've used ubuntu. i hear mark shuttleworth has upgraded to every new release rather than doing a fresh install. in the past i disabled all the extra none supported Canonical repos and used the basic repos for all the updates, but i think that is done for you automatically nowadays.

    the closer you have your system to how it came i.e. fewer extra software/repos, customization etc, the easier and smoother your upgrade should be.

    i'd still give it time and don't upgrade straight away because hopefully any upgrade bugs will be ironed out by then. good luck. i'll be doing the same upgrade too :cool:

    EDIT: this isn't something i know about, but it's worth mentioning - if you have an encrypted home directory, or complete encrypted filesystem, make sure you don't make a silly mistake that will lock you out of all your data :)

    You can always try the liveCD first, will give you a good idea if your hardware will work. I've dist-upgraded 2 machines no problems, but am waiting before I upgrade my main laptop.

    Cheers, Nick
