Oh, nevermind. If you use it locally or use X11 forwarding (it runs fairly well over SSH even remotely), the downloader retrieves the standard install script and everything is the same as before.

This is actually much nicer, since the downloader is a much smaller file to copy over the network and eliminates a transfer step. Nice!

The only problem is that I can no longer figure out a way to install/upgrade Mathematica from the command line, which made it easy to automate installation on multiple machines running in our lab environment. Am I missing something? Is there a way to turn off the GUI on the download tool and just do it through the CLI?

Hmm, I have donloaded the installer on my Ubuntu 5.15.0-40-generic x86_64 yesterday, but nothing happens after execution. No window, no process, nothing. I contacted support and they proposed a reboot, which I did. Today, the linux installer is even not visible in the portal :( Any hints how to resolve this?
