Tor Browser not launching on Ubuntu 22.04

Question

I update to Ubuntu 22.04 and Tor Browser is not working anymore. I removed Tor Browser and when I tried to re-install it by running "torbrowser-launcher", I get the following error message:

    gui.move(

Thanks for your help!

Answer 1

You can fix this by going into the __init__.py file and changing the lines (98) in /usr/lib/python3/dist-packages/torbrowser_launcher/:

gui.move(
            (desktop.width() - window_size.width()) / 2,
            (desktop.height() - window_size.height()) / 2
        )

To:

gui.move(
            int((desktop.width() - window_size.width()) / 2),
            int((desktop.height() - window_size.height()) / 2)
        )

Another solution is posted on the official GitHub: https://github.com/micahflee/torbrowser-launcher/issues/636 (which in general does the same)

Both solutions are valid. I assume it will be fixed in the next update.

Explanation gui.move expects two integers, but can get two floats from the division. Therefore explicit casting to int is needed.

Answer 2

I have Ubuntu 22.04 and Tor Browser not launching (Error 404...) Well. But if I go, in the terminal, to

/Downloads/tor-browser-linux64-12.0.6_ALL/tor-browser

and type

  ./start-tor-browser.desktop --verbose

then Tor-Browser works, I do not why. Every time I start my system, I must do the same in this way
