Dash runs on python2 and older software so not all of the dependencies are downloading. I cannot find a workaround.
You should be able to manually download the dependencies yourself... the issue will be identifying exactly which packages (and which version of each package) that you need to make it work.
Getting an Electrum Dash desktop wallet for Windows 10 is not a problem it works fine but trying to install it on Ubuntu using sudo commands is just not working.
What specific errors are you getting when attempting to install the packages on Ubuntu?
