Can I skip over releases?

I bought Dell Inspiron N5040 yesterday and it seems to have 32bit Ubuntu 10.10 installed. I want to upgrade to 12.04 LTS using network installation. Note, updater can't find 12.04.

Furthermore, if I change long term to normal releases then updater can find 11.04, but it will fail because on an authentication error.

Since you bought this yesterday, I would advise you to go with a clean 12.04 install. –  fossfreedom Jun 9 '12 at 15:00
    
@fossfreedom : I installed Chromium OS (troll face). Note, i had to use prebuilt image, because compiling it requires 64bit system. After i got it installed on systems HDD and flash working, it was beautiful. Then I realized, i could just run it inside Ubuntu and clean installed 64bit 12.04 LTS. Just helpful tip for someone who is assuming that "10.10 > 11.04 > 11.10 > 12.04." will just work - it does not (trying to fix that will just waste your time). –  Margus Jun 10 '12 at 8:18

This thread suggests a direct upgrade is impossible I'm afraid. That concurs with what I thought when I saw your question too, as I'm sure I've seen this asked before. I would suggest backing up then installing clean for the best experience.

It is ... clean, because its new. –  Margus Jun 9 '12 at 13:28
    
Then you can skip the back up :-), though I'm afraid I'm still fairly sure Ubuntu doesn't support upgrades that skip a release unless it's LTS to LTS :-( –  Garry Cairns Jun 9 '12 at 13:32
