Launching Tor using Activities method gives 404 error

Launching Tor Browser app using Activities method gives "Download Error: 404" error in a small window. tor & torbrowser-launcher packages were both installed by sudo apt command from standard Ubuntu repos.

If you launch the application from the terminal do you get useful information?

Here is Terminal stuff:
john@Desktop:~$ torbrowser-launcher
Tor Browser Launcher

Warning: Ignoring XDG_SESSION_TYPE=wayland on Gnome. Use QT_QPA_PLATFORM=wayland to run on Wayland anyway.
Downloading Tor Browser for the first time.

Does the Warning re XDG have any significance?

The file trying to be downloaded doesn't exist
https://dist.torproject.org/

That's what 404 means. Seems like the package needs updating to point to the right file.

You may be able to download the file manually then point the installer at it. It's not something I use so can't dig much deeper. Possibly the command will have a man page and you can use a manually downloaded file to make this work

Ubuntu has a snap package for Tor
https://snapcraft.io/install/tor-mkg20001/ubuntu
or try downloading and installing from the Tor project

@ Bernard Stafford Contacted author of Snap version of Tor re problem on running Tor & Tor Browser. His was the only Snap I found for Tor & Tor Browser. Also, raised it as an issue on the GitHub.

Not sure if this is an issue. Using Tor Browser packages from standard Ubuntu 222.04 repos gives a 404 problem. So I've just tried your 'version' of Tor from https://snapcraft.io/install/tor-mkg20001/ubuntu
It didn't create a Ubuntu launcher and nothing happens in Terminal with invoking tor or tor-launcher. Please clarify if your snap is meant to include use of Tor Browser.

Neither snap version nor Ubuntu repos versions of Tor & Tor Browser work.

Thanks Bernard Stafford, that solved my question.
