Upgrading from the command line?

Question

I would like to know how to upgrade to Ubuntu 10.10 from 10.04 from the cli?

Answer 1

You'll first need to make sure update-manager-core is present (it may already be installed):

sudo apt-get install update-manager-core

Next, run:

sudo do-release-upgrade

You may need to check /etc/update-manager/release-upgrades and change the line:

Prompt=lts

to:

Prompt=normal

for the release to show up.

Answer 2

You can do

sudo do-release-upgrade

for command line updating

(This is actually the same as for Ubuntu Server)

Answer 3

if you run the command 'sudo do-release-upgrade -d' through ssh then use a screen, because the upgrade process will turn off ssh -> close the default port and open a new one ( it will inform you of this new port ), so:

ssh USER@HOST

screen -S upgrade

sudo do-release-upgrade -d

open a new terminal on client computer:

ssh -p PORT USER@HOST

screen -d

screen -r upgrade
