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?
