AMD firmware issues after clean Debian 10 install

[H4NS0N]

I have made the move from my Debian 8 to 10 via a clean install. During the installation I use the option to search the internet for additional firmwares or other stuff.
After a successful installation, it tries to boot up, and I have no chance to see what it actual says. I have restarted so many times now, that I got the idea of what it says like "can't probe to PCI" or something, and that it requires an AMD firmware which is missing.

I have googled me to that I could try secure boot and open the "sources.list" to add following text "contribute non-free" behind the lines in the list, so it might find the missing firmware. After that I try to update/upgrade, but is won't allow it due to secure boot that has some security protocols so it is disabled by default. I then tried adding the lines "--allow-unauthenticated" and "--allow-insecure-repositories" with no luck either. My graphic card is an AMD Vega64, and it seems that Vega54 has some issues to? In a youtube video a guy in the comments has exactly same issues with a 54 card --> https://www.youtube.com/watch?v=26AraxvDTYY
Where the uploader refers to some websites for kernel bugs. So it seems that AMD Vega graphic cards has issues in the new Debian 10?

You could try gdebi'ing in the bullseye driver if you have the firmwares for the card installed...

I get greeted by this during the boot --> https://imgur.com/a/EuoUSyO
After that a wall of text is raining down, then the screen goes black with the "_" blinking in top left corner.
In the secure boot I am not able to do anything update/upgrade wise no matter what I do. So it seems I am doomed with the Debian 10.

A friend of mine found this, and said I might be in same situation, that I am using a stable version, where the testing/unstable might be more fit for me at the moment. Source: https://unix.stackexchange.com/question ... t-friendly

(that guy is also using Vega graphics, just on an APU), so it might be Vega.

AFAIK UEFI secure boot has nothing to do with insecure or unauthenticated APT repositories.
Please post the contents of /etc/apt/sources.list and any file in /etc/apt/sources.list.d/.
Also post the output of

Thanks for you help I really appreciate it. Here is some pics of the outcome --> https://imgur.com/a/4Kz77hQ
I have edited the source.list back to what it was originaly. the /etc/apt/sources.list.d/ just opened a empty file "new buffer".
