how to install wicd on Ubuntu 10.04

Please remove the network-manager package from terminal type

sudo aptitude --purge remove network-manager

Then if Wicd fails to connect after you install it, make sure that the only entry in your /etc/network/interfaces file is

auto lo

iface lo inet loopback

You can change the contents of this file by pressing alt + f2, then typing gksudo gedit /etc/network/interfaces
if you are using Gnome, or replace gedit with kate if you are using KDE.

This will allow you to view and edit the /etc/network/interfaces.
You can ignore lines that start with #.

If after reboot wicd still doesn't works please copy and paste here the content of:

/etc/NetworkManager/nm-system-settings.conf

Hello Marco Braida
thanks for your help.
Could you be specific in helping me to acces this interfaces file!?
thank you

Open a Terminal from the menu Applications → Accessories → Terminal and type or better copy and paste the row below:

sudo aptitude --purge remove network-manager

give your user password when requested, you don't see nothing when you type it, then press enter.

Then copy and paste the row below:

gksudo gedit /etc/network/interfaces

make sure that the only entry in your /etc/network/interfaces file is

auto lo

iface lo inet loopback

Save and exit, then to reboot type:

sudo reboot
