Installing Tor from the development repository
The Tor images in the official Debian repository are not as up to date as those from the Tor
Project. We'll use the Tor Project's development repository to retrieve the latest software.
This is especially important when you are running a bridge, as the bridge and the pluggable
transport software are updated frequently.
The latest instructions as well as the latest GPG fingerprint can be found on the Tor Pro-
stallation procedure, but you should cross-reference them with the published instructions.
Edit /etc/apt/sources.list by adding the following lines:
deb http://deb.torproject.org/torproject.org wheezy main
Next, add the GPG key used to sign these Tor packages:
gpg --keyserver keys.gnupg.net --recv 886DDD89
gpg --export A3C4F0F979CAA22CDBA8F512EE8CBC9E886DDD89 | sudo
apt-key add -
Then, issue the following command:
sudo apt-get update
The Tor Project recommends that you add the GPG key ring with the following command:
sudo apt-get install deb.torproject.org-keyring
Tor needs an up-to-date time as it enforces the time validity on certificates. In a later
chapter, we'll show you how to keep time with a dedicated Real Time Clock ( RTC ). For
now, update your clock from the Network Time Protocol ( NTP ) as follows:
sudo ntpdate -b -u pool.ntp.org
