You have to run following command prior to installing the newest driver:

sudo apt install build-essential dkms

You can also check the following article: https://support.displaylink.com/know...on-ubuntu-20-0

Please give that a try and let me know if it helped.

Hello,

i have both packages installed and the driver version 5.3.1 is installed and working properly together with the older kernel 5.3.0-62.
It stopped working with the delivery of the newest ubuntu 18.04 kernel version 5.4.0-42.

I tried again to uninstall der displaylink driver. Reboot with the newest kernel. Install all updates. Ensure that build-essential and dkms is installed and tried again to install the displaylink driver as described in article 1944022-how-to-install-displaylink-software-on-ubuntu-20-0 with the same result.
If i switch back to the older kernel it directly start working again.

It seems to be that the driver is incompatible with the actual ubuntu 18.04 kernel.
