I just have installed Ubuntu 10.10 , but when I enter update in the terminal I get this message :

No command 'update' found, did you mean:
 Command 'uupdate' from package 'devscripts' (main)
 Command 'lupdate' from package 'libqt4-dev' (main)
 Command 'lupdate' from package 'qt3-dev-tools' (main)
update: command not found

Would you please help me if you have any idea?

10.10 has reached end of life and is no longer supported. You should install 12.04 instead. – psusi Jul 23 '12 at 13:04

update is not a command. apt-get is the command-line tool for handling packages. update is an option to this command.

It is used to synchronize package index files from their sources via the internet.

sudo apt-get update

To apply these updates, run it with the option upgrade

sudo apt-get upgrade

This installs the newest versions of all packages currently installed on your system.

Additionally, if you want to get updates and apply them by just one command update, you could add the following line in your ~/.bash_aliases

update = 'sudo apt-get update && sudo apt-get upgrade'

Besides, you should really consider moving away from 10.10 as it has reached its end-of-life status. – Cumulus007 Jul 23 '12 at 23:48
