How to update Ubuntu 10.10 to Ubuntu 11.04 (Natty Narwhal)

Hello everybody.

Two days ago, Canonical released the Ubuntu 11.04 (Natty Narwhal) and in this version was include many features that can be checked in ubuntu-news.org. To do the update, open a shell and run:

sudo update-manager -d

After run, will be opened a window called Update Manager. Follow the instructions in this window to complete the update.

However, in my case, when I’ve Installed the Ubuntu by the first time, I’ve divided my hard disk in 3 partitions of the following way:

/
/home
/swap

How I prefer to reinstall the Ubuntu, doing that I just need to install it in / (root partition) and all data kept in /home will be preserved. With that, I will leave the system clean but I will take to reinstall the programs again.

That’s it. I will start my update/installation right now. See you next time.

How to give root privileges to another user in Ubuntu

Hello folks.

In this post we will see how we can give to another user the root privileges using sudo command. Before of all, let’s explain what is sudo.

In the Linux, there is a account called root. This one, can do anything in your system without restriction. By default, Ubuntu leave this account locked, you cannot do login with it. You will have access as root using the command sudo that was configured when you created the user during the installation.

So, to give access of root to another user, open a shell and run:

sudo adduser [user name] admin

Where user name is the user you would like to give root privileges. For example:

sudo adduser kde-devel admin

The command above will add the user kde-devel to the admin group. After that, if you would like to remove it, run:

sudo deluser kde-devel admin

That’s it folks. See you next time.
