Why is “No new release found” when upgrading 10.04 to 12.04 LTS?

i am not seeing 12.04 LTS available for update in Update Manager. i followed the update instructions, and set to lts release only. when on normal release, i see only 10.10. i wish to upgrade to 12.04 LTS.

what am i missing?

my data is backed up, but i have at least 2 yrs of programs installed and i would not like to lose all those programs and configs for various services and such. otherwise i would do a clean install.

suggestions? or more specific instructions please.

thanks. pete

This question was marked as an exact duplicate of an existing question.

What Ubuntu version are you running at this time? – Mitch Aug 21 '12 at 19:27
10.04 LTS currently. – olyanderson Aug 21 '12 at 19:28
um... why did you close? there is no exact duplicate... i did the update path from 10.04 > 10.10 > 11.04 > and as you may have guessed by now, THERE IS NO UPGRADE PATH TO 12.04 LTS - per all your instructions, sudo cmd's ecterra... bottom line, something is janked up in the apt or update configs and is a bug of sorts. reopen this ticket. also, if you can post the example of exactness, i would enjoy taking at look at. remember, i followed your instructions, and no 12.04 LTS ever shows up. i'll be awaiting your responses... thanks, oly – olyanderson Aug 24 '12 at 21:04
further more i am currently at 11.04 and im already see degradation in simple functions, like bash not tab completing properly... help! – olyanderson Aug 24 '12 at 21:07
what worked for someone else, obviously isnt working for me... keep that in mind ... – olyanderson Aug 24 '12 at 21:07

Make sure that you have a Backup of everything you absolutely can't afford to lose.

Then just press Ctrl+Alt+T on your keyboard to open Terminal. When it opens, run the command below.

sudo apt-get update

sudo apt-get dist-upgrade

Then see if you have the option to upgrade to 12.04. If not then

do-release-upgrade -d

Update: if the above gives you trouble, try:

sudo apt-get update && sudo apt-get upgrade

sudo apt-get install update-manager-core

do-release-upgrade -d

after doing the above, it states 10.10, not 12.04 LTS. What am i missing? thanks – olyanderson Aug 21 '12 at 22:59
awaiting the next step, do-release-upgrade -d did not set to 12.04 LTS. – olyanderson Aug 22 '12 at 17:39
Try update-manager -d – Mitch Aug 22 '12 at 17:49
nope, still no 12.04 LTS option,,, ponders why it was closed. becuz i didn't do it fast enough? that's really bad support to close a ticket without resolution or feedback from the last cmd avised to execute..... sighs... – olyanderson Aug 24 '12 at 21:06
