Unable to install Tor browser on Ubuntu 25.04 for Raspberry Pi 5

I followed instructions in the following page.
https://linux.how2shout.com/how-to-install-tor-browser-on-ubuntu-22-04-lts-jammy/#3-update-ubuntu-2404-or-2204

and got the following error message.

$ sudo apt install torbrowser-launcher
Package torbrowser-launcher is not available, but is referred to by another package.
This may mean that the package is missing, has been obsoleted, or
is only available from another source

Error: Package 'torbrowser-launcher' has no installation candidate

I am running on Raspberry Pi 5 with Ubuntu 25.04

I also notice that in the following page.
https://ubuntuhandbook.org/index.php/2021/01/install-tor-tor-browser-ubuntu-20-10-20-04/

The website https://deb.torproject.org/torproject.org is missing the plucky directory.

The tor browser installation is not found. Can someone please create the plucky (for ubuntu 25.04) directory and add the required files.

Hello.
torbrowser-launcher is a package from Ubuntu (or more exactly from Debian), not from the Tor project. It should be available in the universe section of Ubuntu repositories.
Also, from the debian description I understand that torbrowser-launcher is just an installer that downloads Tor Browser from Tor Project’s website and uncompresses it in your machine. I suggest that you do so manually, see the download page. Don’t worry about updates, every time you launch Tor browser it downloads them automatically, if there is any.

The download file offered in the download page is tor-browser-linux-x86_64-14.5.2.tar.xz
That is for the x86_64 architecture. While my hardware is a Raspberry Pi 5. Which is arm architeture.

There’s Pi-Apps that you can get. Tor is on there. Unofficial though, and hasn’t been updated in a while… I think you might be out of luck on the Arm Architecture.

I am able to install Pi-Apps following the instruction in the following page.
https://github.com/Botspot/pi-apps#to-install-pi-apps
I also attempted to install Tor browser from Pi-Apps.
The Tor browser installed. But nothing happens when I try to run it.

I think there is no formal support form tor browser on arm platform.

https://sourceforge.net/projects/tor-browser-ports/files/

This is the best non official version of tor browser. It is also the version installed from Pi-Apps.
