I am trying to boot Debian 10.7 from a usb drive. When I try to boot it said "amdgpu requires firmware installed." I am using a AMD Ryzen 5 2400G processor (with Vega graphics). How do I fix this? Thanks in advance.
Also, I seem to be only able to access the terminal in recovery mode so all the "fixes" I tried will be attempted through the terminal in recovery mode.
I have attempted to search for a solution using google already. I came across the Debian website which provided a solution (https://wiki.debian.org/AtiHowTo)). However, when I try to apply the solution, I can't complete the "apt update" part as when I try to execute that line in the terminal it outputs "Could not resolve 'deb.debian.org'". I then thought it was maybe a network problem and I tried to ping google (184.108.40.206) but the terminal said "Network is unreachable". I tried to search for a solution to that but every "fix" seemed to involved a command that I don't have and I can't really install anything since I can't connect to anything. I am using ethernet and my internet was fine when Debian was installing (as it seemed successfully install). I don't know what is going on, can someone help me please. Thanks in advance again.
