Public bug reported: After doing a fresh install of Ubuntu Desktop 16.04.2, I used Ubuntu Software Center to install Tor Browser (Tor Browser Launcher). I then click on the Tor icon to start the initial download of the Tor Browser Bundle. The download completes, but the subsequent signature verification fails with a message "SIGNATURE VERIFICATION FAILED". The message also suggests that I might be under attack (very unlikely) or that there might be a networking problem. I am using a stable network, have not had network problems with other applications, and repeating the download, even after redoing the Ubuntu installation, does not change any behavior.
