I'm using Ubuntu 12.10 (quantal) and I recently installed Tor (32 bits) following the instructions on the Tor project's page. Then I started the script after having it extracted from the console and got this:

master@ubuntu:~/tor-browser_en-US$ ./start-tor-browser 

Launching Tor Browser Bundle for Linux in /home/master/tor-browser_en-US
./start-tor-browser: 225: ./start-tor-browser: ./App/vidalia: not found
Vidalia exited abnormally.  Exit code: 127

Then I ran Vidalia from the console and:

master@ubuntu:~/tor-browser_en-US$ vidalia

(<unknown>:11354): IBUS-WARNING **: Unable to load /var/lib/dbus/machine-id: Failed     to open file '/var/lib/dbus/machine-id': Permission denied
master@ubuntu:~/tor-browser_en-US$ vidalia

(<unknown>:11358): IBUS-WARNING **: Unable to load /var/lib/dbus/machine-id: Failed     to open file '/var/lib/dbus/machine-id': Permission denied

And after Vidalia's GUI opens I get the error prompt about starting Tor:

"Vidalia was unable to start Tor. Check your settings to ensure the correct name and location of your Tor executable is specified."

How can I start Tor?
