Command Not Found when running 'svn'

Question

I installed the Ubuntu 12.04 from a usb drive. I am having issue with my wifi connection. I tried to update the network adapter but ran into this problem with the svn command.

sudo svn checkout http://svn.madwifi-project.org/madwifi/trunk/ madwifi-ng

I was using the codes from Madwifi installation for Atheros card in Karmic koala however, I am stuck on step 7. It says the sudo svn command cannot be found when I entered in the step 7 code. I tried to find similar issue in the thread but could not find it.The thread I was reading from is closed. I have a Atheros Wireless Network Adapter and was trying to update it so I can use my wifi. Right now I am using a Ethernet.

Install the subversion package. Then try again. The svn binary, the Subverion client, is in that package.

By the way, the "Command not found" error also hints on this package:

$ svn checkout ....
The program 'svn' is currently not installed.  You can install it by typing:
sudo apt-get install subversion

Also, there's no need to run svn commands with elevated privileges like sudo. I understand you're just following a how-to there, but just don't do that.

Having said all that, zooming out on your initial issue about Wireless, I don't think this will work. Karmic Koala (9.10) is really old and Atheros wireless drivers aren't in the madwifi driver anymore nowadays. If I recall correctly, this is now merged in the mac80211 driver. Please ask a more specific question about your Wireless issue.
