first, I would like to apologize. I am not an experienced Linux user. However, I used to run Ubuntu Linux on my computer.
I recently wanted to try something new and fast and snappy as Elementary OS. The problems appears when I boot up my Elementary OS from USB and then click on Try Without installing. The speakers start buzzing. It sounds like a weird static noise that will not stop. Even full installation does not help.
The second problem is with the resolution. Only choice I have in my system is 800x640 and system can not detect my laptop screen.
The last problem is with the terminal. I have tried to get some update via sudo apt-get update and so on. It does not allow me to do anything due to insecure(8) manpage repository error.
My laptop is ASUS Zenbook 14 UM431DA (Ryzen 5 3500U and 8GB RAM).
I just want to mention that I do not have any sound or resolution problem with Ubuntu, that works perfectly fine.
Is there anyone who could help me with this issue ?
