Can't upgrade with cdromupgrade

Question

I am try to upgrade to 12.04 from 11.10 using alternative CD. I run this command

sudo gksu "sh /media/iso/cdromupgrade"

after mounted iso as CD. Its gives this error "An upgrade from 'oneric' to 'precise'"

My error message

Yes, this is a very odd way of doing it Arul. Alternatively, you could just boot a LiveCD and upgrade the current install from the Installer. — Jjed, Apr 26, 2012 at 18:09
@SirCharlo I tried this command it gives "No new release found" — Arul, Apr 26, 2012 at 18:39
@JacobJohanEdwards My internet is very slow. That's why using this method — Arul, Apr 26, 2012 at 18:40
@Jjed when you do this does it follow the same process as do-release-upgrade? I've done it from the CD before and ended up loosing a load of programs. Ive not lost anything with ' do-release-upgrade'. — Andrew S, Jul 28, 2017 at 3:37

Check my image carefully. There is a typo in codename oneiric is correct not oneric.

sudo gedit /etc/lsb-release

and correct this error.

DISTRIB_ID=Ubuntu
DISTRIB_RELEASE=11.10
DISTRIB_CODENAME=oneiric
DISTRIB_DESCRIPTION="Ubuntu oneiric"

Now everything is working fine.
