These are the instructions from the official Tor Browser User Manual in case the Ubuntu torbrowser-launcher package hasn't updated the gpg key that is required to install Tor Browser. Unfortunately the Tor Browser developers change their signing key that is used to install Tor Browser at periodic intervals which makes the torbrowser-launcher package from the default Ubuntu repositories not work because it is not as up-to-date as the current version of Tor Browser. The Tor Browser Launcher Settings app is also installed along with Tor Browser. After installing Tor Browser, it can be launched by searching for tor in the Dash and clicking the Tor Browser icon. torbrowser-launcher handles downloading the most recent version of Tor Browser Bundle for you, in your language and for your architecture.
