can not update and upgarde

[mori64]

when i want update and upgrade terminal shows this output :

0 upgraded, 0 newly installed, 0 to remove and 0 not upgraded.
so what happened ?

Theres nothing new to upgrade :-) it's normal

[mori64]

no it isn't normal because now I'm using Ubuntu 10.4 so normally when i do
sudo apt-get upgrade
it must begin to upgrade . am i wrong?

[Hippytaff]

ok you want to upgrade to 10.10?

Thats different to this command...I got this confused for ages


sudo do-release-upgrade

or check upgrade manager and tick the box that enables release upgrades :-)

apt-get update and apt-get upgrade install the regular updates for the current release.

Release upgrade command is mentioned above by Hippytaff.

And the box for release upgrades is under System > Administration > Software Sources > Updates > Release Upgrade > and select Normal Releases.
