I am trying to setup Ubuntu OS (more specifically Lubuntu) on my Raspberry Pi 4. Firstly, I download the file from IoT page which is specific for Raspberry Pis and then I flash it into the card (which is 16GB with usable 14.8 gb) with balenaEtcher. When it's done it shows confirmation in green and the process is complete (and sdcard is ejected out automatically if that is normal). Then I inserd my SD into the raspberry pi and it starts the process, after that I type in the username and the new password... When it's finished processing the lot I type in "sudo apt install lubuntu-desktop" then it starts processing normally but at the end (or maybe also between) it gives me some failed tasks which are probably the cause for the failure. If I then try to type "startx" it doesn't work and it says that i must install xinit but even when I do it of course doesn't work. Maybe it's because at the end of flashing it makes 2 partitions i think and it then thinks that it doesn't have any space left?
I tried whole bunch of different scenarios like. I downloaded 32-bit, or 64-bit, or tried to install stock ubuntu, and I followed exact steps by the video on YT first one that pops up (and between every attempt I formated SD) but nothing worked. Everything stops at the end. So I would need some help and I would be grateful for your resposes :)
