I humbly seek assistance with my DEll D6000 docking station.

I am unable to install displaylink-drivers because it conflicts with evdi install. I'm unable to uninstall evdi because it appears to be not installed.

Distributor ID: Ubuntu
Description:    Ubuntu 22.04.3 LTS
Release:    22.04
Codename:   jammy

I got the following info from AI:

It seems like there was an error during the installation of the displaylink-driver package due to conflicts with the evdi package. To resolve this issue, you can try the following steps: Remove the problematic packages: sudo dpkg -r evdi sudo dpkg -r displaylink-driver Update the package manager: sudo apt update Reinstall the displaylink-driver package: sudo apt install displaylink-driver By following these steps, you should be able to install the displaylink-driver package without any conflicts.

======

I have tried the above and it didn't work. :

peter@pzx:~$ sudo dpkg -r evdi
dpkg: warning: ignoring request to remove evdi which isn't installed
peter@pzx:~$

Here is the output from trying to install the displaylink-driver:

peter@pzx:~$ sudo apt install displaylink-driver

The issue was resolved as follows:

sudo apt remove displaylink-driver 
sudo apt update 
sudo apt install dkms libdrm-dev 
sudo apt autoremove 
sudo ./displaylink-driver-5.8.0-63.33.run 
reboot 
sudo ./displaylink-driver-5.8.0-63.33.run

What we need to do is fix the "Error: Another EVDI distribution detected":

  1. Figure out if there are any previous installs using: dpkg -S /opt/displaylink . If you get "no path found matching pattern", then skip to step 3
  2. sudo apt purge package_name if any were found
  3. sudo rm -rf /opt/displaylink/
  4. Retry your installation

The cause of this is straightforward. Look at the "pre-installation script" (preinst) in evdi_1.14.1-7_amd64.deb and you will find the following:

#!/bin/bash

if [[ -e /opt/displaylink/evdi.tar.gz ]]
then
  echo >&2 "Error: Another EVDI distribution detected"
  exit 1
fi
