How to add repositories manually in ubuntu

Do this at your own risk. Modify the default Ubuntu sources.list only if you understand what you're doing. Mixing repositories can break your system. For more information see the Ubuntu Command-line Repository guide.

Create a backup of your current list of sources.

sudo cp -p /etc/apt/sources.list /etc/apt/sources.list_backup

Note: sudo - runs the command with root privileges. cp = copy. -p = prompt to overwrite if a file already exists.

Edit the list of sources:

sudo nano /etc/apt/sources.list

or using a graphical editor:

gksudo gedit /etc/apt/sources.list

Note: To use your local mirror you can add "xx." before archive.ubuntu.com, where xx = your country code.

Example: deb http://gb.archive.ubuntu.com/ubuntu jaunty main restricted universe multiverse indicates a repository for Great Britain (gb).

Here is a sample sources.list. At the end have been added repositories for Medibuntu and Google:

#deb cdrom:[Ubuntu 8.10 _Jaunty Jackalope_ - Release i386 (20081029.1)]/ jaunty main restricted

wbar: a quick luanch bar( similar to avant and cairo dock)

wbar is a quick-launch bar (not a dock) that has an appearance similar to Avant Window Manager and Cairo Dock. It is GTK (Gnome) based but can work in all desktop environments. It does not require a compositing manager to be installed and is therefore quicker and more suitable for low-end hardware systems. It is the default in the Google gOS desktop and is available as a .deb package from Google. Download and install (from the command-line Terminal): wget http://wbar.googlecode.com/files/wbar_1.3.3_i386.deb sudo dpkg -i wbar_1.3.3_i386.deb Start wbar with custom start options (e.g. by pressing alt+F2). Here is an example: wbar -isize 48 -j 1 -p bottom -balfa 40 -bpress -nanim 3 -z 2.5 -above-desk Here is another example: wbar -above-desk -pos bottom -isize 60 -nanim 1 -bpress -jumpf 0.0 -zoomf 1.5 For a full list of command-line startup options, see: wbar --help Tip: If you want the "wave" effect just increase the -nanim value. I like the icons to just pop up so I do...
