I'm using linux mint 20.3 on ThinkPad L14 Gen2 with AMD CPU. When I try to install amdgpu-install (it's necesarry for Displaylink driver) i get this message:

After reboot, screen is black and I cannot see log in window.
Search missing firmware, but I cannot find them.
I tried many version of amdgpu-install, from 20.20 to 21.50
Anyone know what I should do ?
