Would you like to post your output? Also "lsb_release -a", "uname -a" and "apt search libdrm-dev"

Well I'm assuming that the German is the same as my English version! :-) The only difference i have is that I am running kernel 5.4.0-29.generic...maybe try enabling the focal-proposed repository?

I hope so! Okay I will give it a try. Thanks

You could also try "sudo apt -f install" to fix any missing dependencies before re-running the installation...

[Jeins]

Tried that before. Don't help. And also with new kernel, I get the same error

Interesting...

I've done a "apt search libdrm" on my system for comparison. Output is as follows:

Maybe you are missing one of these? Just a thought...

Only thing extra I had to do even though on Intel graphics I
had to make /usr/share/X11/xorg.conf.d/20-displaylink.conf
contain:
Section "Device"
Identifier "DisplayLink"
Driver "modesetting"
Option "PageFlip" "false"
EndSection

not this:
Section "Device"
Identifier "Intel Graphics"
Driver "intel"
EndSection

Now I have the same output, but that don't change anything.
