You might have grabbed the wrong iso. There are two ISOs for Ubuntu, one is desktop which comes with a desktop and the other is server which only comes with a text console.

You can install a desktop onto a server image if necessary, however I would recommend just using a desktop iso and don’t bother with adding on and setting up all the desktop software.

If you want to be able to select text, copy and paste, I just SSH from Windows Terminal or Mac iTerm2

Alternatively if it is a desktop iso then you might have accidentally installed a package that broke things or have gone a tty interface. There’s so many different possibilities it’s going to be hard to help more.

Private sites that people upload torrents to. A lot of them have requirements like “upload at least 1 content that we don’t have” and “must maintain a seed ratio of x”. Most that I’ve seen either have closed registrations, requiring someone to invite you as a referral, or they have interviews to make sure you’re not malicious”.

I’ve always wanted to be in one because every once in a while I can’t find content that’s old/obscure and it’s super annoying and supposedly private trackers have a bunch of old/obscure content as-well as super new stuff like blu ray rips and native stream rips.
