Install tor in Ubuntu

Do not use the packages in Ubuntu's universe. They are unmaintained and out of date. That means you'll be missing stability and security fixes.

You'll need to set up our package repository before you can fetch Tor. First, you need to figure out the name of your distribution. A quick command to run is lsb_release -c. Here's a quick mapping:

Ubuntu 10.10 is "maverick"
Ubuntu 10.04 or Trisquel 4.0 is "lucid"
Ubuntu 9.10 or Trisquel 3.5 is "karmic"
Ubuntu 9.04 is "jaunty"
Ubuntu 8.10 is "intrepid"
Ubuntu 8.04 is "hardy"
Debian Etch is "etch"
Debian Lenny is "lenny"

Then add this line to your /etc/apt/sources.list file:
deb http://deb.torproject.org/torproject.org <DISTRIBUTION> main
where you put the codename of your distribution (i.e. etch, lenny, sid, maverick, lucid, karmic, jaunty, intrepid, hardy or whatever it is) in place of <DISTRIBUTION>.
Then add the gpg key used to sign the packages by running the following commands at your command prompt:

gpg --keyserver keys.gnupg.net --recv 886DDD89
gpg --export A3C4F0F979CAA22CDBA8F512EE8CBC9E886DDD89 | sudo apt-key add -

Now refresh your sources and install Tor by running the following commands (as root) at your command prompt:

apt-get update
apt-get install tor tor-geoipdb

To start:
make sure the tor and privoxy services have been started

sudo /etc/init.d/tor start
sudo /etc/init.d/privoxy start

Then start vidalia.....
