I'm trying to install the Ubuntu Server operating system, but unfortunately at the last stage of installing, the installation logs, the 'Reboot now' button is not showing up. I've waited for fifteen minutes. It is an older laptop (Dell Inspiron 15 5000 series i7. I'm pretty inexperienced with this kind of thing. Is it just slow or is there something wrong? Also, my Ethernet connection is not working properly. I don't know if this has something to do with it.
I also can't backtrack by pressing the Esc key or a 'back' option. The version I am using is "ubuntu-26.04-live-server-amd64".
