After the installation there will be a lot of downloaded packages in /var/cache/apt/archives/ . You can free up some diskspace by running: 

# apt clean 

## D.4.9. Create a User 

Use the adduser command to create a new user account: 

# adduser myusername 

You will be prompted for a full name and a password. 

The normal Ubuntu configuration is to allow this new user to administer the system using sudo . To set this up, first create an admin group and add your new user to it: 

# addgroup --system admin 

# adduser myusername admin 

You can now use the visudo command to add these lines to the end of /etc/sudoers , so that any user in the admin group can administer the system: 

# Members of the admin group may gain root privileges %admin ALL=(ALL) ALL 

If you don’t want to follow this configuration, then remember to set a root password: 

# passwd root 

## D.5. Installing Ubuntu using PPP over Ethernet (PPPoE) 

In some countries PPP over Ethernet (PPPoE) is a common protocol for broadband (ADSL or cable) connections to an Internet Service Provider. Setting up a network connection using PPPoE is not supported by default in the installer, but can be made to work very simply. This section explains how. 

The PPPoE connection set up during the installation will also be available after the reboot into the installed system (see Chapter 7). 

To have the option of setting up and using PPPoE during the installation, you will need to install using one of the CD-ROM/DVD images that are available. It is not supported for other installation methods (e.g. netboot). 

Installing over PPPoE is mostly the same as any other installation. The following steps explain the differences.
