Introduction to Linux - A Hands on Guide
This guide was created as an overview of the Linux Operating System, geared toward new users as an exploration tour and getting started guide, with exercises at the end of each chapter.
For more advanced trainees it can be a desktop reference, and a collection of the base knowledge needed to proceed with system and network administration. This book contains many real life examples derived from the author's experience as a Linux system and network administrator, trainer and consultant. They hope these examples will help you to get a better understanding of the Linux system and that you feel encouraged to try out things on your own.

johnsfine, thanks a lot for all this detailed information. Very instructive.
So I'm still in the prepare partitions window.
I made some changes so that it now looks that way :
device type mount point format? size used
/dev/sda1 ntfs (nothing) (unselected) 50 GB 25 GB
/dev/sda2 ntfs (nothing) (unselected) 100 GB 3 GB
/dev/sda3 ext4 / (selected) 20 GB unknown
/dev/sda5 swap (nothing) (unselected) 4GB unknown
Yes it's starting normally.
I didn't notice any errors.
There are quite a lot of things that need to be installed now, I'm waiting for your instructions (you said yesterday that there were procedures to do once the installation is complete so that the next reinstallation would be easier).
There is no admin user at the moment, I'm not sure I have the admin rights but I think it's safer not to.
Maybe I can remake a packages.txt so that we can compare ?
Don't I need to set up my internet connection first ?
I know how to do that, but I have a small question. I'm using a secure one. I was wondering if there was a way to type the password in an encrypted way, because if I type it just like that it can be accessed in the internet options.
I thought you already were connected to the internet, sorry
Of course you need to be connected to the internet first in order to check for updates.
I'm not sure what you mean with 'type the password in an encrypted way'. And what do you mean by accessing the password in the internet options?
Normally you set up a connection using the network manager in Ubuntu. That one takes care of encrypting the password when communicating with your device. Can you tell me how you usually connect to the internet? Using wireless or cable? Do you have a DSL connection or other?
wireless. There's an icon in the panel where I can choose my network. It then opens a window called wireless network authentification required.
I can type my password here.
If I do though, and then right click on the icon, then edit connections, then wireless, then the name of my connection, then a window appears intitled 'allow access' : allow application access to keyring ? The application 'nm-connection-editor (usr bin nm-connection editor) wants to acces the password for 'network secret for myconnection in the default keyring. If I (or someone else than me) then press 'allow once' and then go to 'wireless security' and 'show password', the password is visible, even though no admin password was asked during the whole procedure.
I'm afraid someone else with more knowledge on Ubuntu has to kick in on that one. Normally I would say that your password is encrypted and only available to you. Of course if you leave your computer with a session open then anyone can get access to your password while you're away. If you lock your screen then they'd have to know your user password.
I'm not sure but I think that the connections are configured on per user basis, so if you create another user, he'll have to go through the same process to connect to your router. That new user will not have access to your data (unless if you put him in the sudoers group, then he can gain access).
