I have encountered the exact same problem. I have a 20.10 Ubuntu installation and the latest Displaylink driver. Everything was working fine until recent Linux update - I'm not entirely sure, but I think it stopped working after I upgraded to Ubuntu 20.10 from 20.04. I tried to reinstall the driver but it didn't work and I get the exact same error message as above. Is there any solution?

Following message is contained in '/var/lib/dkms/evdi/1.9.1/build/make.log' as suggested by the error output above:

DKMS make.log for evdi-1.7.0+dfsg for kernel 5.8.0-53-generic (x86_64)
Do 3. Jun 16:21:11 CEST 2021
make: Entering directory '/usr/src/linux-headers-5.8.0-53-generic'

ERROR: Kernel configuration is invalid.
include/generated/autoconf.h or include/config/auto.conf are missing.
Run 'make oldconfig && make prepare' on kernel src to fix it.

make: *** [Makefile:746: include/config/auto.conf] Error 1
make: Leaving directory '/usr/src/linux-headers-5.8.0-53-generic'

my guess is that because ubuntu 20.10 switched to the new linux kernel 5.8 and the EVDI modules are not properly configured for it the installations fails. If that is indeed the reason is there a way to configure evdi to be compatible with this new linux kernel ?
