Can't install Draftsight on Ubuntu 18.04

Hi I have been trying to install the latest version of Draftsight (Download for Ubuntu) on my new setup with Ubuntu 18.04. I got the following error messages in Terminal when trying the following:

bruce@bruce:~/Downloads$ sudo dpkg -i draftSight.deb
(Reading database ... 174397 files and directories currently installed.)
Preparing to unpack draftSight.deb ...

dpkg: error processing archive draftSight.deb (--install):

Errors were encountered while processing:

I would appreciate any suggestions you might provide about this !!! Thanks !!!
