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 taht 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.

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