Not able to install Display Link software in Ubuntu 18.04.1 LTS

[situsnow]

Hi,

I am really new to Ubuntu and I would like to extend my laptop to two monitors.

I followed the commands in this link to install but failed as "screen1.jpg" in the attachments.

Using the hints in the error, I got logs as "screen2.jpg" and "screen3.jpg". I also attached the log generated by the support tool -- "mu001143611_2018-08-10T11:18:52.524635.zip"

Using command "lsusb -d 17e9:", I can see one device connected - "Bus 002 Device 003: ID 17e9:6006 DisplayLink", but there's no response on both monitors.

Really appreciate if anyone could help in this issue.

Regards,
Snow
